Visibility of live chat bubble

I have been asked to find out if there's any pattern when it comes to the live chat bubble display. The thing is we currently keep visible not only the Hubspot bubble, but also an extra layer with an avatar as well as this message: "Got any questions? I'm happy to help". I was wondering if we should keep visible only the bubble as that's probably enough for the user. Any thoughts on this? enter image description here

Thanks in advance.
