How to get a new access token via refresh token using Expo Auth Session?

I’m using Google for auth (expo-auth-session/providers/google)

I can successfully login for the first time and fetch an access token and a refresh token. The refresh token will get stored in SecureStorage.

Now at this point, when the old access token is invalidated, I need to use the refresh token to get a new access token, but Expo’s docs don’t really provide any guidance on this part. I have checked their API quite thoroughly, but can’t see anything that helps me retrieve a new access token with a refresh token.

Any guidance would be welcome.
