Answer 1

I think there's a bug in the GORM plugin. It doesn't seem to recognize the databaseName property. It does seem to work if you use ONLY the connection string.
connectionString: "mongodb://username:password#host:port/databaseName"
For details: https://docs.mongodb.com/manual/reference/connection-string/
