Configuring SCIM connector in wizard to connect to Starling Connect

I am trying to connect the SCIM connector by using the wizard from Launchpad ("Target system type SCIM interface").

I am struggeling obviously to provide the correct parameters (Server URL, Port, Service URI, Client secret etc.) to get a successful connection to Starling connect.

As far as I can see all the information is provided in the Starling portal, but I guess I am missing the single important point here.

Can someone advice which information needs to be taken from the Starling portal and be pasted into the right fields of the SCIM connector wizard?

Thanks in advance.

Quick help is very much appreciated as a matter of urgency.

Cheers,

Jörg
