According with this comment in an issue at carbon repository...

Moving to blocked for now and updating it to 3 points.

Moving this ticket to be backlog as it got blocked in sprint 39. The carbon component does not support this functionality so review of other options will need to be done. A spike has been created in this ticket: #1780

Collapse navigation looking good! If I have one nitpick, it's that, while the menu is expanded, the hover text on the expand/collapse button reads "Open menu" when clicking on that button would actually close the menu. Would it be possible to update the hover text on that button to read "Close menu" while the menu is expanded?

Nice catch, thanks @kevinginley ! Fixed on my last commit, should be available to test after the deploy is updated.

It's been updated - looks good @mgaseta!
