Any member of a private team can add new members to that team. To add a new team member from the app:
  1. Go to the team profile for that team from either the Message tab > tap the team name in the app header or Contacts tab > search for the team.
  2. On the team profile screen, tap the Add Members.
  3. Type the name of the person(s) you want to add.
  4. Select the person(s) you want to add from the returned results.
  5. Tap the Next or right arrow.
You can add either co-workers or people from your device contacts to a team. Co-workers are added instantly to a team. Personal contacts, if they aren't already on RingCentral, will receive an invitation to join via email. Once they join, they will be able to participate fully in the team conversation.
