We have added a filter for this so you can customize the menu permission used by our plugin. You will see this in the new version (v4.4.2) of the plugin.
You can add custom code like the following to allow other roles to access the admin dashboard menu of the plugin. Please note that you need to be a WP developer to tackle this (otherwise things can go wrong).
The following EXAMPLE code will allow editors and above to be able to see the admin dashboard of the license manager.
function slm_my_custom_management($permission){
$permission = 'edit_pages';
return $permission;
}
add_filter('slm_management_permission_role', 'slm_my_custom_management');
