As an admin or owner you have access to the team settings (teams.wire.com). In the People tab you are able to change the roles for each person on your team.
A team member is a user that is part of the team. Team members can easily find each other and start conversations. Team members can create and delete conversations, add and remove team members in conversations, and invite guests to a team conversation.
A team admin is a team member with administrator rights, which allow them to add or remove other team members. Team admins can also promote and demote users from members to admins or owners and update team settings. The team can have multiple team admins.
A team owner has the same rights as the admin, plus access to the billing section of a team. The team can have multiple owners. Only owners can invite people as owners to the team.
A partner, for example a client or a contractor, is part of your team. Partners have less rights than team members. Partners can only find team members who are in the same group conversations. They can be added to group conversations by other members of your team. Partners can leave a group conversation, but they cannot create one or change its settings. Partners can not be promoted and demoted. Partners can change their notification settings for a conversation. Team members can find partners by searching for their usernames.
