Help creating an ESI Block

Hi, I tried creating an ESI block but that put the cache in private by default

I want to create a simple function, that i will render custom post list, I want to save this block in “Public Cache for 5 mins”

In the docs and developer hooks, It only allows to set no_cache and ttl.

What hook can I use to set it to public?

here is my code

echo apply_filters( ‘litespeed_esi_url’, ‘display_most_read’, ‘Most Read ESI block’ );

Functions.php

add_action( ‘litespeed_esi_load-display_most_read’, ‘most_read_block_content’ );
function most_read_block_content() {

…
//return processed content
}

Much appreciated
