I have attempted many solutions provided on Stack Exchange to obtain a refresh token, and they all fail. Below is my whole controller. As you can see, I have included $client->setAccessType('offline') and $client->setApprovalPrompt('force').
In addition, I have ran the revoke token many times, and I have gone into my Google Account here (https://myaccount.google.com/permissions), and removed access. None of these attempts provided me with a refresh token when I made a new authorization.
