Failed in sending the link of mail invites while creating new user with viewer role.


I have implemented the PMM with the docker installation way.
PMM is implemented in AWS ec2 instance.
Also, i have added AWS RDS instance for monitoring.

We are in need to create a read only user so that we can give to team for monitoring.
From the tool, we are having one admin user.
so while inviting user, with viewer role its giving error.

Also SMTP server is configured and we have tested by sending test mail.

So is there any way to add a viewer role user in PMM tool?
