Question concerning a tablet dashboard

I'm planning on getting a Samsung Galaxy A11+ and creating a wall mounted dashboard. I started on the one in the screenshot below (It needs work). I've read that some use a "Kiosk" software and create a kiosk based tablet.

I was planning on installing the HA Companion app, then just bring up the desired dashboard. This seems more straightforward than the Kiosk route. Is there any issue with simply displaying the tablet in the companion app?

-Thanks
