My activity filter provides several options like groups, memberships, updates etc. but it doesn’t mention new posts from a cpt I added. How can I fix that?

This is my code used to create this cpt:

    add_post_type_support( 'diary', 'buddypress-activity' );

function customize_page_tracking_args() {
    // Check if the Activity component is active before using it.
    if ( ! bp_is_active( 'activity' ) ) {
        return;
    }

    /**
     * Also don't forget to allow comments from the WordPress Edit Page screen
     * see this screencap https://cldup.com/nsl4TxBV_j.png
     */
 
    bp_activity_set_post_type_tracking_args( 'diary', array(
        'action_id'                         => 'new_diary',
        'bp_activity_admin_filter'          => __( 'Published a new diary', 'custom-textdomain' ),
        'bp_activity_front_filter'          => __( 'Diary', 'custom-textdomain' ),
        'bp_activity_new_post'              => __( '%1$s posted a new <a href="%2$s">diary</a>', 'custom-textdomain' ),
        'bp_activity_new_post_ms'           => __( '%1$s posted a new <a href="%2$s">diary</a>, on the site %3$s', 'custom-textdomain' ),
        'contexts'                          => array( 'activity', 'member' ),
        'activity_comment'                  => true,
        'comment_action_id'                 => 'new_diary_comment',
        'bp_activity_comments_admin_filter' => __( 'Commented a diary', 'custom-textdomain' ),
        'bp_activity_comments_front_filter' => __( 'Diary Comments', 'custom-textdomain' ),
        'bp_activity_new_comment'           => __( '%1$s commented on the <a href="%2$s">diary</a>', 'custom-textdomain' ),
        'bp_activity_new_comment_ms'        => __( '%1$s commented on the <a href="%2$s">siary</a>, on the site %3$s', 'custom-textdomain' ),
        'position'                          => 100,
    ) );
}
add_action( 'bp_init', 'customize_page_tracking_args' );
