Over the years using Unity Collab, and I've been added to many organizations using Unity Collab not owned by me (most of them from students that added me to check their project or some freelance work).
When all the Collab to Plastic happened I suddenly got a lot of organizations on my Dashboard / Cloud, not owned by me, and from old projects I don't care anymore, and also I'm not sure I can contact the owner to ask them to remove me.
So how can I voluntarily leave such organizations?
I'm not being billed for those so I can't "cancel" my subscription.
And I see no option to leave the project / organization.
