Operators of an open or group channel can restrict select users from sending messages to the channel using the mute feature. A muted user remains in the channel and is allowed to view the messages but they can't send any messages until they're unmuted by the operators. Operators can mute and unmute users in channels using the following code.
Note: You can also use
unmuteUserWithUserId()as they have the same functionalities. See our API reference for more information.
