How can I distribute asset licenses to team members?

If I buy for example 5 licenses of an editor extension like 2D Toolkit, how can I distribute the 4 licenses I’m not using myself to teammembers who have their own asset store account?

Pretty old question, but others might find this as well.

This page says:
“Once you have purchased multiple seats (copies) of an Asset you can allow team members/others to use the Asset without any issues.”

So if you buy several licenses, then I think you just share the project with the other members of the team, and they can then legally use the asset or assets because you own licenses for them to use. I would see this as the licenses are then owned by the company, so if at some point one developer stops working on this project, another should be able to replace that developer and use the same license.
