"Got an error on GET to https://api.slack.com/api/auth.test: invalid_auth"

For the past few days, when i try to use emojifs, it fails with invalid_auth. Here's what a run looks like:

$ emojifs -vv

It was working fine last week.

$ emojifs --version
emojifs 0.2.0
$ python3 --version
Python 3.8.5

I have another user who is encountering the same issue.
