To enter a private group channel, a user must be invited by members who are already in the group channel. On the other hand, an invitation isn't required to join a public group channel. Only members of a group channel can invite new users to the channel.
You can also determine whether the newly invited user can see past messages in the channel or not. You can manage the settings on Sendbird Dashboard
