Confused AF regarding trauma kit So it says it heals during "recovery phase" but I've not a clue what the recovery phase is?

I've tried google but nothing.

Logic and some small experience with CCGs made me assume that it came after an action or maybe after a turn but there has been ZERO scenario where I've actually managed to use a trauma kit; it always says something along the lines of "Pills cannot use any of her surgeon items on slick".

It doesnt say in the tooltip anything about being used for specific injuries or whatever so I'm FULLY stumped here.

Begging for help!
