How to send an admin message on Sendbird UIKit?

[Problem/Question]
I maintain a web chat page which is implemented with React-JS.

I’ve got a request to add {user.nickname} left message, when the user leaves the group channel. I found that I can use ChannelHandler.onUserLeft() to detect someone left the group channel, but cannot found a way to send an admin message. (Just like current {user.nickname} joined message).
Do you have any way to achieve this?

Hi @Eueddem_Kim. You can send an admin message to a channel on Sendbird Dashboard or using Chat Platform API.
Also, there are some auto events in Sendbird. You can find it under Settings > Chat > Channels > Auto message.
