New phone - 2FN - Need set up key for Authenticator App

I have to set up authenticator app for new phone. I set up 2FN on my old phone. I don't have the QR code to link team viewer with my existing free personal account for the app. Disabling 2FN doesn't work because I need the authenticator app to be already set up to get the security code. Where can I get the QR code for my existing team viewer account again?
