Add custom entry in settings panel

Is it possible to add a custom entry in the settings panel (shown in screenshot)?

I found this helpful forum thread but it seems to be outdated and I have to do other things in Kirby 3.

Until now I’ve been hooking the ‘page.delete’ function but that seems bad UX wise.
I have also tried adding a custom field via plugin but putting the feature where it belongs seems more fitting, also I’m not that good with Vue.

Bump? I feel like this could interest other users as well.
