To add a user to your Enterprise team, you must be an owner or admin (or a manager, if the option to invite users has been enabled for the manager role). You can also control access by assigning roles to your users.
To add users to your Enterprise team:
Sign in to your InVision Enterprise here: your-team-name.invisionapp.com
In the main navigation, click Team.
On the People tab, click the pink + sign at the top right.
Enter the invitees’ email addresses, separated by commas, and click Next.
Verify that the email addresses are accurate, make any role changes, and then click Invite.
To let people join your team without requiring an invitation, you can set up Approved Domains. With Approved Domains enabled, anyone can sign in to the team by using an approved email address—i.e., an email address from an email domain that a team owner has previously approved.
