So If I add a collaborator in my clean room and left it for days, then I will be charged 50$ for each day?
Where can i see these charges?

I have created 2 workspaces in two different regions in my azure account and created a clean room in one of the workspace, added the other workspace as collaborator in that clean room. I have the clean room active but haven't seen any charges reference to adding collaborator in my monthly azure billing?
