I think this one may help https://www.cnet.com/how-to/how-to-move-google-authenticator-to-a-new-device/
Well base in my experience in autheticator i was use both pc and my android smart phone but i have my back up in pc because the pc version has the ability to backup your authenticator that you can use in the future..

Try to look to show your secret key and take note and save it somewhere safe. like in the paper and hide it in your wallet.. that you can recover and use it in other autheticator pc version or other devices..
