You must have been hearing some typical Balkan nationalist propaganda pseudo-history.

Not that I'm adverse to pseudo-history mind hehehehehe... I've also heard tons of nationalist pseudo-history for decades now, coming from all sides of that particular brand of fantasy - pretty much every single people in Eastern Europe has its own nationalist spin attached hehehe... Reading some of the nationalist mass produced "history" books around Eastern Europe is priceless entertainment!
The Albanoi were an Illyrian tribe like many others, Albania the kingdom is a medieval creation, strangely by Charles of Anjou hehehehe. Also if I implement another kingdom related to Illyrians - it's most likely going to be Dardania - they are integral to the timeline. So, sadly there's little chance of implementing Albania atm. They might have been an interesting addition for some I'm sure.
