When the current app doesn't provides menu-items (or the user doesn't have the rights to access them), the mobile burger menu should fallback to the user menu instead of an empty one (like on the App Switcher). Steps to reproduce (on mobile): - on a newly database, install only "notes" app - connect as 'demo' user - open the notes app - open the burger menu => as there is no submenus, burger menu is empty. task-2345001 closes odoo/odoo#84692 X-original-commit: odoo/enterprise@f8e85c39e6 Signed-off-by: Adrien Dieudonné (adr) <adr@odoo.com>
