MT Enhanced installed but not functioning (Trados Studio 2022)

Just updated to Trados Studio 2022. Installed Language Weaver (working fine) and MT Enhanced plugins, the latter to use with a Google API.

The MT Enhanced plugin installs fine, it shows up in Project Settings and can be selected. I ran the Google API through the Google API validator - it's valid.

Now - in the actual project's Translation Results windows, I'm getting results from my TMs, a result from Language Weaver... but no results from MT Enhanced. No error messages either.

TL;DR: MT Enhanced is installed properly, but doesn't seem to be function and isn't giving an error message.

Am I doing something wrong?
