None. ONLY remaining INtern train to B-gr is to black mountains=Montenegro/Bar. Line to Budapest is under complete rebuild-part in Serbije mostly replacement bus (payable), first sector is ready and has new trains, but for now does not take passes (fare is very low). Greece, Macedonia, BiH have NO INtern. trains at all, Albania never ever had them, but is also out of any pass. Using a pass is a waste of money anyway-local fares for what still runs-if they can get it done-is very low, even compared to recently post-covid reduced IR fares.
