Please allow me to make an additional confirmation of the question asked at the URL above.
Currently, the authentication is done using a refresh token.
We have checked the following URL and found that the refresh token does not have an expiry date set
In the reason why the refresh token expires, the application verification does not state that the refresh token is set to expire.
https://cloud.google.com/docs/authentication/token-types#refresh
https://developers.google.com/identity/protocols/oauth2#expiration
Can I assume that app verification does not affect the expiry date of the refresh token?
We would like to confirm this because if the token information already registered will no longer be available, this will cause more work for the user.
