Hey, thanks for the quick response!

Yes.

I'm using an adapted version of [this solution](https://github.com/jdagdelen/mondigy) that was mentioned on a [previous thread](https://support.prodi.gy/t/problems-exposing-a-custom-database-class-via-an-entry-point/3943).

I haven't tried the entry points option, will check that and let you know.
