The preset is the ceiling
A receptionist cannot reach finance, and an accountant cannot reach collaboration requests. That is enforced at the API, not by hiding a menu item.
Staff are hired into a preset — receptionist, manager or accountant — and the preset is the screen. A receptionist sees six things, an accountant five, and nobody sees the owner's console.

A receptionist cannot reach finance, and an accountant cannot reach collaboration requests. That is enforced at the API, not by hiding a menu item.
Every payment taken and every check-in is recorded against whoever did it. If a figure is ever disputed, the line says who was at the desk.
Someone leaves, you stop their preset, and their sessions end in the same moment — not whenever a token happens to expire.
The presets already exist — pick one and the hire gets their screen immediately.
