Hi,

You can solve directly from the UI without touching XML. You just need to go to Settings → Technical → User Interface → Menu Items, search for your menu, open it, and under the Groups field, remove the unwanted group (e.g. some_admin_right) and add only the group you want (e.g. base.group_no_one). Once saved, the menu will immediately reflect the new access rights, and you won’t need to manually adjust it again after module updates.

You can add or remove the user groups from here.

Or try with the following code

<menuitem id="my_menu"

          name="My Menu"

          parent="base.menu_custom"

          action="action_my_model"

          groups="base.group_no_one"/>

Hope it helps
