Alphabet index when viewing All Items

Not sure exactly how to describe what I am talking about in words, so have attached a picture from my iOS 1Password app (see right hand edge, area in red circle). Several years ago, this "alphabet" on the side of the All Items view was available in the desktop app, but has been missing for a long time. I am unable to find it in any Settings. This is extremely helpful to jump right to the general part of my 300+ item long vault. Is this still available in the desktop app, or can it be brought back?

Thank you
