Ah, yes thanks! This is an known issue in the Auth Library that we're slowly trying to fix as well and sorry to see that this also bit you all.

The existing access token will be invalidated (not copied) in the future from the builder.

// only those are used in gRPC CallCredentials to fetch request metadata.
