Pump lets you add unlimited users to your team as admins or viewers once you've linked your AWS account.
To add team members to your Pump account, navigate to Settings > Team Members > Invite team member.
Everyone is added as a 'viewer' by default, i.e., they don't have the permissions to add additional AWS accounts. You can further make them an admin if you need to. If there are any other user-related permissions you need, please email us at [email protected].
