How do I invite another developer to my project

How do I invite another developer to my project while I am using free tier

Techniquement ce n’est pas opérationnel, un autre développeur ne peut pas avoir accès à votre compte Studio Ai

What I mean is working as a team on a project and inviting a team member to work with you. It usedto be possible before but I cannot do that again

You can add Co-Developers via Google Cloud IAM. You can add them in specific projecs and assign them roles like Editor or Owner.
