How to create custom URLs for Custom Post Types

We have various custom post types on a site and we’re trying to customize the URLs for such posts. Some example post URLs:

current: /core-principles/?core_principle=88
desired: /core-principles/2-respect-for-human-rights

current: /contents-of-the-framework/free-prior-and-informed-consent/?guidance_topic=0
desired: /contents-of-the-framework/free-prior-and-informed-consent/1-fpic-definition-and-overview

So the desired URL format is:

/name-of-post-type/name-of-post/name-of-topic-if-present

Oddly, when viewing a post in WP admin, the permalink is listed correctly but the full page content does not load properly.

In our post-types directory, this is in principles.php (governing the first example post above):

<?php

/**
 * Principles
 */

namespace App;

add_action( 'init', '\App\principles_post_type' );
function principles_post_type() {
    register_post_type(
        'principle',
        array(
            'labels' => array(
                  'name'               => __( 'Core Principles', TEXT_DOMAIN ),
                  'singular_name'      => __( 'Core Principle', TEXT_DOMAIN ),
                  'add_new'            => __( 'New Principle', TEXT_DOMAIN ),
                  'add_new_item'       => __( 'Add New Principle', TEXT_DOMAIN ),
                  'new_item'           => __( 'New Principle', TEXT_DOMAIN ),
                  'edit_item'          => __( 'Edit Principle', TEXT_DOMAIN ),
                  'view_item'          => __( 'View Principle', TEXT_DOMAIN ),
                  'all_items'          => __( 'All Principles', TEXT_DOMAIN ),
                  'search_items'       => __( 'Search Principles', TEXT_DOMAIN )
            ),
            'public' => true,
            'publicly_queryable'  => true,
            'exclude_from_search' => false,
            'has_archive' => true,
            'hierarchical' => false,
            'rewrite' => array( 'slug' => __( 'core-principles', TEXT_DOMAIN ), 'with_front' => false ),
            'show_in_menu' => true,
            'show_in_admin_bar' => true,
            'supports' => array( 'title', 'revisions' ),
            'menu_position' => 6,
            'menu_icon' => 'dashicons-thumbs-up'
        )
    );
}

and this is in guidance.php (governing the second example post above):

<?php

/**
 * Guidances
 */

namespace App;

add_action('init', '\App\guidance_post_type');
function guidance_post_type() {
    register_post_type(
        'guidance',
        array(
            'labels' => array(
                  'name'               => __('Operational Guidance', TEXT_DOMAIN),
                  'singular_name'      => __('Operational Guidance', TEXT_DOMAIN),
                  'add_new'            => __('New Operational Guidance', TEXT_DOMAIN),
                  'add_new_item'       => __('Add New Operational Guidance', TEXT_DOMAIN),
                  'new_item'           => __('New Opertional Guidance', TEXT_DOMAIN),
                  'edit_item'          => __('Edit Operational Guidance', TEXT_DOMAIN),
                  'view_item'          => __('View Operational Guidance', TEXT_DOMAIN),
                  'all_items'          => __('All Operational Guidance', TEXT_DOMAIN),
                  'search_items'       => __('Search Operational Guidance', TEXT_DOMAIN)
            ),
            'public' => true,
            'publicly_queryable' => true,
            'exclude_from_search' => false,
            'has_archive' => true,
            'hierarchical' => false,
            'rewrite' => array('slug' => __('contents-of-the-framework', TEXT_DOMAIN ), 'with_front' => false),
            'show_in_menu' => true,
            'show_in_admin_bar' => true,
            'supports' => array('title', 'revisions'),
            'menu_position' => 5,
            'menu_icon' => 'dashicons-analytics'
        )
    );
}

The permalinks are set to “Post name”: /sample-post/

I also tried adding a rewrite rule in principles.php:

function core_principle_rewrite_tag_rule() {
  add_rewrite_tag( '%core_principle%', '([^&]+)' );
  add_rewrite_rule( '^core_principles/([^/]*)/?', 'index.php?core_principle=$matches[1]','top' );
}
add_action('init', 'core_principle_rewrite_tag_rule', 10, 0);

But no dice. How can I set all these custom post type URLs to follow the desired format? Do I need to adjust that rewrite rule or is there some existing setting that should be changed or something?

I’m using WordPress Version 5.2.4 with the Sage starter theme: https://roots.io/sage/
