pre-populated TCGA workspaces

Hi

I have access to TCGA controlled datasets, and I was able to link my FireCloud account to my eRA Commons.
I can see the list of controlled TCGA datasets available in the data library,

however, I do not see prepopulated TCGA workspaces in the list of workspaces.
I was expecting to see these workspaces show up once I link to my eRA Commons account,
where I would for example see the controlled-access PON VCF file etc...

Where can I find these workspaces so I can clone them?

Thanks!
