Put it on your phone. It runs inside a container, so on top of stock android. All your normal phone stuff is still there and running. Worth noting android has good support for mouse and keyboard.
Edit: user below pointed out that this does not appear to be an app, which kinda makes it a weird choice? Seems like there are still better solutions like Userland, Andronix, and LinuxDeploy
In this specific github entry it mentions flashing, and with my setup, I would prefer not to flash something onto my phone without some sort of backup.
Unless there is a userland app I can install that I seem to be missing.
