Add variable or secret to organization

Hello, I have a lot of projects under my organization, all need the same secrets and organization.

So I tried to add secrets and variables directly to the organization with e.g.:

$ agola --token $AGOLA_USER_TOKEN -u $AGOLA_GATEWAY projectgroup variable create --projectgroup org/ercole-io --name variables -f ./variables.yml

While this is NOT documented, it worked well, infact I can see them in “Root Project Group” settings.
But sadly it doesn’t actually work, I think during the run they are empty.

Is it a bug that it doesn’t work?
Is a bug that I have been able to add them?
