[4.0] Hide "Add module to the dashboard" from Manager group

[Quy]

Steps to reproduce the issue

Log in to the Administration backend as a manager.
Click Add module to the dashboard icon.

Actual result

You don't have permission to access this. Please contact a website administrator if this is incorrect.

You identified the error but I think your solution is wrong.

The code says that this should be present
if ($user->authorise('core.create', 'com_modules'))

and a manager does have create access - however a manager does not have access to the admin interface

[chmst]

The condition must be <?php if ($user->authorise('core.manage', 'com_modules')) : ?> in com_cpanel default.php, not core.create .
