Greetings,

I have a CPT “events” that I want to display on the activity feed. I stumbled upon this page: https://codex.buddypress.org/plugindev/post-types-activities/ which tells you how to implement it.
I have added
add_post_type_support( 'page', 'buddypress-activity' );
to the custom-bp.php which works and indeed shows a post once I add a new event.

However, the message it shows is a bit generic (Name wrote a new item) which I would like to change (including featured image).

In the above-mentioned link it does explain how to do this (changing the text) but for some reason, I can’t make it work. I added the following code as mentioned to my custom-bp.php but it just does not change the message:

function customize_page_tracking_args() {
    // Check if the Activity component is active before using it.
    if ( ! bp_is_active( 'activity' ) ) {
        return;
    }
 
    bp_activity_set_post_type_tracking_args( 'events', array(
        'component_id'             => buddypress()->blogs->id,
        'action_id'                => 'new_blog_page',
        'bp_activity_admin_filter' => __( 'Published a new page', 'custom-domain' ),
        'bp_activity_front_filter' => __( 'Events', 'custom-domain' ),
        'contexts'                 => array( 'activity', 'member' ),
        'activity_comment'         => true,
        'bp_activity_new_post'     => __( '%1$s posted a new <a href="%2$s">event</a>', 'custom-textdomain' ),
        'bp_activity_new_post_ms'  => __( '%1$s posted a new <a href="%2$s">event</a>, on the site %3$s', 'custom-textdomain' ),
        'position'                 => 100,
    ) );
}
add_action( 'bp_init', 'customize_page_tracking_args' );

Also, in the best case I would like to add the featured image to it which is clickable (exactly how it does it for a normal blog entry).

Can somebody tell me what I do wrong?
