Custom post type with multiple taxonomies

I’m building an custom post type with multiple taxonomies.

I use https://generatewp.com/ to quickly fill in all the info I need and strip out the stuff I don’t need.

I do the same for the custom taxonomies.

When I generate the code with https://generatewp.com/ it gives each post type and taxonomy a function but that is not necessary because you already have the cpt function.

How do I place the taxonomies within the cpt function?

<?php
if ( ! function_exists('ot_uitje_cpt') ) {

	// Register Custom Post Type
	function ot_uitje_cpt() {

		$labels = array(
			'name'                  => _x( 'Uitjes', 'Post Type General Name', 'ot_uitje' ),
			'singular_name'         => _x( 'Uitje', 'Post Type Singular Name', 'ot_uitje' ),
			'menu_name'             => __( 'Uitjes', 'ot_uitje' ),
			'name_admin_bar'        => __( 'Uitje', 'ot_uitje' ),
		);
		$rewrite = array(
			'slug'                  => 'uitjes',
			'with_front'            => false,
			'pages'                 => true,
			'feeds'                 => true,
		);
		$args = array(
			'label'                 => __( 'Uitjes', 'ot_uitje' ),
