Hi @Irina Q, thank you for reaching out! I recommend using connected projects. With Connected projects two separate teams or organizations can work together on a shared project. This makes it easy to design together, share resources, and hand off files smoothly—without paying for extra seats.
Here’s how it works:
- The party which creates the project and sends a request to connect is the host.
- The party which receives the request to join the connected project is the external team.
The external user will only have access to that specific project. You can read more about how connected projects work here: Guide to connected projects
Let me know if you have any further question!
