What is does it say typing when you open a chat?

As an AI language model, I do not have access to the specific chat application or platform that you are referring to.

However, in general, some chat applications may display a message or notification when someone is typing in the chat. This usually appears to provide real-time feedback to the user that someone is typing a response. It can also help prevent interruptions or overlapping messages in the conversation.

If you need more specific information about a particular chat application, please provide the name or platform so I can assist you better.
