Can the menu pane be hidden?

Is there away to hide / show the menu pane on the left?

you can create a new project and open the link in a new window Cayenne Docs

Sorry but what I mean is how do I expand to full screen mode as the DOCs are not clear to me on this point. They talk ablout using “share link” but I haven worked out how to get the share link menu to come up.

what do you mean by this?

In the DOC’s i
Share link is talked about but it is not clear to me how to use “share link” and after opening up the new link you are supposed to be able to expand the screen to full size.
Or is there another way to expand the screen to full size ie without the menu bars?
