How to request Slovak death records?

My great-grandfather's family is from Trebisov, Slovakia. I want to know how I could request death records for my 2x great grandparents because I can't find their births and I would hope that getting the records would help me go back farther on those sides of family, also because hopefully it would be a similar process for marriage records or any other records after civil registration because I don't know anything about my great-grandfathers siblings and suspect most of them did not immigrate or died after civil registration started. I read a little bit on family search's wiki about this but it didn't really help me at all and most of the information on there seemed outdated. If anyone has done this before or has tips it would be nice to get an explanation or run down on how I could do this, thanks!
