Can you try this:

function custom_toolbar_link($wp_admin_bar) {
    $wp_admin_bar->add_node(array(
        'id'    => 'clear-all-caches',
        'title' => 'Clear All Caches',
        'href'  => false,
    ));

    // Try 'debloat-delete-cache' as the action (matching the page slug)
    $urlDebloat = wp_nonce_url(
        admin_url('admin.php?page=debloat-delete-cache'), 
        'debloat-delete-cache'
    );
    
    $wp_admin_bar->add_node(array(
        'parent' => 'clear-all-caches',
        'id'     => 'clear_debloat_cache',
        'title'  => 'Clear Debloat Cache',
        'href'   => $urlDebloat,
        'meta'   => array('title' => 'Clear Debloat Cache'),
    ));
}
add_action('admin_bar_menu', 'custom_toolbar_link', 999);
