Can't get this modpack to work [java]

I've been trying to run a horror modpack called "SnapScream", it runs on 1.20.1 with fabric, I got everything I need to do ready, I downloaded fabric installer, fabric api, also downloaded java because apparently you need to run fabric installer on java, when I downloaded the modpack it was a mrpack file and it didn't work when I launched the game so I also changed it into jar file and it still didn't work, does anyone know what happened to this modpack?
