Something like that. Emulators also give the ability to emulate cameras using pictures or video feeds.

They just need to set up a Google play equipped emulator, set the picture as simulated camera input and put in the inputs to the emulator (also automatable)

May have to stream a video of the screen into a scanner app, but shouldn't be difficult anyway.

One of the forms of digital ID in use in my country now has a new way to use it, which the government websites use now. You always needed a mobile device for this one anyway (phone holds the private keys and you have to enter the PIN 1 or PIN 2 depending on whether you're authenticating or authorizing something), but it used to be that you could enter your ID code and get prompted for the PIN (with a verification number to make sure you're responding to the prompt you think you're responding to), now it's either on-device from the default browser to the app, OR on desktop you have to scan a QR code that's a moving target, it changes a couple of times a second so you couldn't send a screenshot to someone else to scan. This is meant to prevent scams where someone gets you to just enter your PIN over a phone call.

I don't know if the google thing is similar though or if it's a static QR there.
