Can I create a link that automatically opens the chat pane?

I know there are a lot of URL config switches for launching Jitsi Meet with a certain configuration. For example, adding “#config.prejoinPageEnabled=false” launches without the pre-join page.
Is there a config URL parameter for launching Jitsi Meet and showing the chat window right away? Many users don’t realize that it has a chat function due to the interface design’s lack of text labels, so it would be useful to be able to show the chat pane automatically within the interface via a URL parameter when desired. I didn’t see anything documented in the user guide, but I understand that is not complete.
