Answer of Sandeep is correct. But once you know the group name. You could also go to the Settings->Users & Companies->Groups (developer mode enabled). Search on the group name (the group which is connected to this menu item), and validate that your user is part of the group.

You may want to add another group to the inherited list (see inherited tab). That why, new users to lets say the emlyoeen group will be automatically be added to your group that currently used by this module menu item(s).
