Best way to use tablet with fully kiosk browser and room specific HA dasboard?

I have a nice lenovo wall tablet up and running with a full version of the fully kiosk browser. Have the integration in HA and have also build a (test) dashboard.
Now I am wondering how to show the dashboard in the FKbrowser on the tablet. Can I manage that directly from the HA system? Or is that only possible through the FKbrowser config?

Is entering https://my.hassio.ip//test-dashboard/0 the way to get it going? How to prevent other users getting access to other things in HA than what is on that test-dashboard? Can I have the side bar, all, devices, etc. hidden (not accessible) for the wall-tablet users?
Is that trough the user (settings) or also through an other setup?

Set up a non admin user account for the tablet and restrict the user to the tablet dashboard only.

Thanks. But how to get the dashboard on the tablet? As mentioned through the url in the kiosk browser? Or can this be done with the integration? Or is the integration more a kind off remote control for the tablet (kiosk)?

You set it in fully kiosk.

Ok thanks. Will give it a try.
