Moderate Participant’s entry to a Session

In a knock-enabled Room, a user needs to wait until the Moderator grants them permission to join the Session. The EnxRoom.approveAwaitedUser() method allows the Moderator to approve a user’s entry and EnxRoom.denyAwaitedUser() method is used to decline a user’s entry to the Session.

Methods:

• EnxRoom.approveAwaitedUser(ClientID, Callback)
• EnxRoom.denyAwaitedUser(ClientID, Callback)

Event Notifications:

• user-awaited – Notification to the Moderator when a user awaits their permission to join Room.
• room-allowed – Notification to the user when the user is permitted to join Room after waiting on a wait-for-moderator or knock-enabled Room.

// Moderator is notified about awaited user
room.addEventListener("user-awaited", function(event, user) {
      // Client Info: user.clientId
      // Create UI for Moderator Interaction to allow or deny 

	// To allow
	room.approveAwaitedUser(clientId, function(success, error) {
	     // Check Success / Error result
	});

	// To deny
	/*
	room.approveAwaitedUser(clientId", function(success, error) {
	     // Check Success / Error result
	});
	*/
});

To manage awaited users when moderator joins late

If the Moderator joins after the participant(s) have sent a request to join the Session in a Knock-enabled Room, then the Moderator can get the list of participants awaiting approval using room.awaitedParticipants. You can utilize this attribute to build UI for Moderator controls to handle pending approvals.

// e.g. room.awaitedParticipants

[
	{	"clientId”: "String", 
		"name": "String" 
	}
]
