Enable removing or clearing the history of last messages

[mcai]

It will be convenient if we can add some buttons to enable users either remove specific message or clear the whole history of last messages besides the input box.

I agree. While this gets implemented, you can try to clear your local storage. It will wipe the whole history.

This will only work if you are not using a cloud project. For cloud projects, the history is saved in a DB.
