I am trying to create a Databricks Clean Rooms instance, I have been following the video from Databricks youtube channel.

As I only have one workspace, to create a clean rooms I have added my own Clean Room sharing identifier,

when I do that I get the error message:

"Request collaborators should include the creator at most one time."

I have asked for feedback in Databricks webpage, but I received no answer so far.

Is anyone able to help me? Is this the right way to create a Databricks Clean Room just for testing?

Thank you in advance.
