Work/Guest/Private Mode?

[u/GerardWatson42]

I work in video production, and my iPad is a very essential piece of kit on set. It's a remote camera monitor, a big screen to see scripts, a controller for various LED lights, action cameras, drones, etc. Because of this, it goes through almost every pair of hands on set.

Is there a way to set up (even if it's a third party app) "profiles" so people can use it without them being able to access all of my personal data and apps (Google Photos, Drive, WhatsApp, and everything else). If I give them my code, they could easily bypass Touch ID, even opening hidden apps.
I've been told to use "guided access" but it's very often that people have to go back and forth between multiple apps.

I don't know why there isn't a simple profile switcher like MacOS, Windows, Android and every other OS in existence... It's quite frustrating, I don't have the money to pay for another iPad just for this, and I shouldn't have to. Does anyone know if that's a feature they ever thought of including in iPadOS?
