The teams page is where you manage and control who has access to your Freshpaint account.
There is an optional capability to specify Roles and Access to projects & environments for each user - for more details, see Role-Based Access Control (RBAC).
To add a teammate to your account click the Add Teammate button. This will open a prompt asking for their email:
Enter their email and click Send Invite. This will send them an email with a link to be added to your account. Make sure they check their spam folder for the email. The link will expire after one week.
