typing
Indicate that Participant is typing in this conversation.
You should call this method to indicate that a local user is entering a message into current conversation. The typing state is forwarded to users subscribed to this conversation through onTypingStarted and onTypingEnded callbacks.
After approximately 5 seconds after the last typing call the SDK will emit onTypingEnded signal.
One common way to implement this indicator is to call typing repeatedly in response to key input events.
