Help... I'm new to Google Cloud and/or Workspace but I need a Data Studio Pro license

Hi experts!
We are working with DataStudio (LookerStudio actually) for a while now.
However, we want to automate the dashboard sharing to (new) clients.
Therefore I need a Data Studio Pro account. But this is where the questions begin..
I’m the owner of the dashboard, but I can’t create a DataStudio Pro account because it doesn’t have a workspace account? I now created a workspace account, but as soon as I want to log-in to the Data Studio world in GoogleCloud, a error pops up.
Is there anyone who would like to help me, or, do you know where I could get some Google supportdesk/people to help me out?
Help is much much appreciated!
Thanks in advance.
