Calculate the occupied space by the user

Hello. I want to host an additional copy in my company, but for this use I will need to know exactly how much space on my storage each employee has used. You need to know exactly the actually used space, not the starting quota.
Tell me how it is possible to see it?

Hello,

It’s not possible yet. See https://github.com/Chocobozzz/PeerTube/issues/1888

Thank you for efficiency. I will wait for this opportunity-)
