We want to remove item Mass Actions Menu

Hello,

We want to remove Merge, Doc Merge, and Doc Merge to PDF from the Mass Actions Menu. Can anyone provide a solution for this? We have tried the following solution, but it didn’t work:

<?php
$viewdefs['EDoc_Email_Documents']['base']['view']['recordlist']['selection']['actions'] = array(
    // Keeping only the mass PDF merge button
    array(
        'name' => 'mass_update',
        'type' => 'massupdate',
        'label' => 'LBL_MASS_UPDATE',
        'acl_action' => 'massupdate',
        'type' => 'button',
    ),
    array(
        'name' => 'mass_pdf_merge_button',
        'label' => 'LBL_MASS_PDF_MERGE_BUTTON',
        'type' => 'button',
        'primary' => true,
        'events' => array(
            'click' => 'list:masspdfmergebutton:fire'
        ),
        'acl_action' => 'massupdate'
    ),
    array(
        'name' => 'mass_delete',
        'type' => 'massdelete', // Define the type for the delete action
        'label' => 'LBL_DELETE_BUTTON_LABEL', // Label for the delete button
        'acl_action' => 'delete', // ACL action for delete permission
        'type' => 'button',
    ),
    // Removed actions
    // array(
    //     'name' => 'merge',
    //     'type' => 'merge',
    //     'label' => 'LBL_MERGE',
    //     'acl_action' => 'merge',
    // ),
    // array(
    //     'name' => 'doc_merge',
    //     'type' => 'doc_merge',
    //     'label' => 'LBL_DOC_MERGE',
    //     'acl_action' => 'doc_merge',
    // ),
    // array(
    //     'name' => 'doc_merge_to_pdf',
    //     'type' => 'doc_merge_to_pdf',
    //     'label' => 'LBL_DOC_MERGE_TO_PDF',
    //     'acl_action' => 'doc_merge_to_pdf',
    // ),
);
