No Admin FE settings: "You must enable configurable_from_database in your config file"

There are no admin settings in Admin FE. "Request failed with status code 400 - You must enable configurable_from_database in your config file."

Pleroma's own documentation on this is incredibly unclear, and I'm even more lost with containerization. Can I set this in `config-override.exs`? Is this something I need to do through `docker exec`?

Seems like admin settings shouldn't be anywhere near this difficult to use and I'm missing something obvious.
