Custom Block editor template for event with tickets

example.php

<?php
// Return a custom order of the default blocks on an event.
// to change the order of the blocks, arrange the lines the blocks are added to the array. 
// To remove a block from being added by default, comment out the line for the block. 

add_filter( 'tribe_events_editor_default_template', function( $template ){

    // initiate our array
    $template = array();

    // default blocks
    $template[] = array( 'tribe/event-datetime' );
    $template[] = array(
        'core/paragraph',
        array(
            'placeholder' => __( 'Add Description...', 'the-events-calendar' ),
        ),
    );
    $template[] = array( 'tribe/event-price' );
    $template[] = array( 'tribe/event-organizer' );
    $template[] = array( 'tribe/event-venue' );
    $template[] = array( 'tribe/event-website' );
    $template[] = array( 'tribe/event-links' );

    // tickets blocks
    $template[] = array( 'tribe/tickets' );
    $template[] = array( 'tribe/rsvp' );
    $template[] = array( 'tribe/attendees' );

    // return the array of blocks with our custom order. 
    return $template;
    
}, 500);


// Prevent tickets from being added again by the plugin. We've already added them in the order we want.
remove_action( 'admin_init', array( tribe( 'tickets.editor' ), 'add_tickets_block_in_editor' ) );

Hi,

This is more or less what i'm looking for, only I can't figure out where I should put this php file.
Can you guide me into the right direction?

functions.php?

@jminexa You can put this code in your child theme's functions.php.

It works like a charm for me!
