Question switch between apps and "returnto" functionality in unity hololens 2 app

I am working on a hololens 2 project where the requirement is to launch Dynamics 365 Remote assist from unity app. once the app is launched, is there any way I can switch between remote assist and my unity app without going to windows menu.

If opening from the windows menu the unity app starts from the beginning not from the screen where I launched Remote assist app. Is there a way I can go back to the same screen?

Also, there is "returnto" functionality for protocol activation in Hololens development
https://docs.microsoft.com/en-us/dynamics365/mixed-reality/remote-assist/protocol-activation
which enables returning to the app once the call is finished.

How do I activate this protocol in unity application ? Is deep linking same as the protocol activation in hololens?

Any help would be appreciated, Thanks in advance.
