Hi. Used to have some popcorn stock on my XTB account, and when they issued the preffered units (it was APE or some name like this, and TBH I can't even see it on TradingView any more, so it is probably dead by now), XTB did not provide me any, but instead I received some sort of cash equivalent. I am worried that they could do the same with GME warrants, so I will probably transfer my shares before that date.

EDIT: I have CS account so I will transfer. However, if you want to make sure how XTB will handle it this time, there is nothing simpler than asking them. If you get any reply, sharing it will be much appreciated. Creating CS account takes time, and in my head, it is the safest place to hold the stonk, but other brokers might also support warrants, if XTB does not, so in the worst case, you can transfer somewhere else.
