I have a Hobby-plan project on my account. My colleague has his own separate Railway account with his own email. I want to transfer the project to his account, but I can't invite him as a member of my workspace (or vice versa) since Hobby doesn't support multiple members, and I can't change my account's email to his since he already has an account under it. What's the supported way to hand this project to him?

I need to transfer the project to his email.
