Cannot assign group for Chronicle access using IAM

[abaz]

Hello, I got an Unauthorized error like the image below "There was a problem. An error occurred during authentication. Please try again, and if the problem continues, contact support."
that's the error response.

I use SSO configuration using Google Cloud Identity.

I have added the role of the email group in IAM: Chronicle API Admin, Chronicle Service Admin, Chronicle SOAR Admin.

But after trying to access from one of the members in the email group, I get an error like the image.

Is there something missing from my configuration?

Thanks
