How to add user to project as internal contributor? End goal of changing project ownership

Hi there,

I’m trying to transfer ownership of a project to another user. When I add the user as a contributor to the project, it says they’re added as an outside contributor (which isn’t what I want to do, but can’t see an alternative way of adding them to avoid that). I am the current owner of the project. I tried to follow this guide: Changing the owner of a project - Bitrise Docs , but couldn’t see the “transfer ownership” button they refer to.

How can I proceed here? There is a workspace that the project is part of which someone else created and then added me to - not sure if that’s causing complications.

TIA
