I got a response from the Firebase Support team . It is not possible to remove the analytics data generated by your teammates during development or during testing phase. They advise to create separate projects for testing and production
Hi Jani,
I hope you're doing well and thank you for reaching out to us. If you
meant like removing the analytics data generated by your teammates
during development or testing phase, then it is not possible. In this
case, we usually advise our developers to create separate projects,
one for test or development phase and for production.
To disable the analytics collection in your app, please check out this
documentation.
If you have any other questions or clarifications, just let me know.
Thank you.
Regards,
