Scheduling Scripts in Claris Cloud Server Console

It's the first time I've tried to use the Claris Cloud console to schedule a script. I'm being shown this screen. The database picker doesn't allow me to specify which account to work with.

Then it throws up this screen.

For comparison, the on-premise dialog allows you to specify which account will be used to open the database.
