To be eligible, the recipient must have a Pro licence and be a member of your team (= in the same console).
If your team is part of a company (= Company) then this last condition is extended to all the company's teams.
Users in the same team can transmit activities to each other independently.
At the end of the transfer, the user is invited to reload the page for the changes to take effect. They then become co-hosts of the activity where possible (or co-admins of the Network), otherwise they become simple participants.
