This github issue seems related to the problem I have: https://github.com/googleads/googleads-php-lib/issues/180
The answer seems to imply that an OAuth2 object should be instantiated and not use the OAuth2TokenBuilder (There is a way to set access_token with OAuth2 but not with OAuth2TokenBuilder). But still, the app has no way to synchronize the access_token refresh part, which is important in a distributed system as multiple instances of php on different servers can refresh the access token at the same time and I'd like to have a way to synchronize the refresh here. (My app was taking care of this before, using a redis distributed lock mechanism so I was in control of refreshing and updating/saving the new access_token). I'm wondering if having my own object implementing the "FetchAuthTokenInterface" is the solution here. This seems a bit complex but maybe this is the way to go? Thanks.
