I'm new to server hosting so how can I see if a data pack is in the default world. I did try on a single player world and it did work.

After following the video tutorial on how to add datapacks to my server I logged in trying to use Player Head Drops from Vanilla Tweaks. I checked the datapack list and there was just Vanilla and Bukkit. I have tested multiple things and it is still yet to work. Please help.
