Hi @suleiry m

I apologise for this delayed reply!

This is a great question! Just like Team folders Team spaces are designed to be shared with users who are on the same account only and therefore you won't be able to share one with an external collaborator.

We always welcome feedback from users -- if you would like to provide feedback to our Product Development Team about this feature I encourage you to post in the product feedback space!
