How to install an old version of an app (downgrade) on F-Droid 2.0-alpha9?

Hi, old versions are displayed on both full and basic flavors of F-Droid, and that’s great! However, how to interact with them? Let’s say I update an app and find out there is something that doesn’t work anymore, so I decide either to downgrade or reinstall. I look at the version list but can’t find a way to choose any of them. Clicking just expands the tag, and long pressing it depends on where you click: if you long-press on the tag itself, then nothing happens, if you do the same on description, it enables text selection. Am I missing something? I searched on gitlab and forum, but could not find a related issue. If that feature is absent, then a good approach would be on long-pressing the tag, a menu emerges and user can install that version. Another way would be adding a button like previous F-Droid did, if I recall correctly.
