A user who is invited to a group channel can accept or decline the invitation. If a user accepts an invitation, they join the channel as a new member and can start chatting with other members. If the user declines the invitation, the invitation is no longer valid.

If the client app is in the foreground, the members of the group channel are notified of whether the newly invited user has accepted or declined the invitation. To do so, implement the
channel(_:didDeclineInvitation:inviter:) methods in the channel delegate. For more information, see the event delegate page.
