Authorization error when opening add-on

I'm currently getting the following error at the bottom of the pane when opening the add-on:

```
Error

Authorization is required to perform that action.

Please report this error
```

The final line is a link that actually just leads to https://wordpress.com/support/ and not to this Github repo.

I've tried removing and reinstalling the add-on and gotten the same results.

Based on the [comments on the Marketplace](https://workspace.google.com/marketplace/app/wordpresscom_for_google_docs/460536350236?pann=cwsdp&hl=en), it doesn't look like this kind of error is universal, but it does appear to be fairly common.

No files or tests are named. Start by reproducing the authorization error when opening the add-on and trace the entry point that renders the error; done means the add-on opens successfully and the “Please report this error” link leads to this repository.
