No it doesn't show anything when I do /datapacks, I did notice that when following along in the video some of the folder names are different though, for example when the people in the video are going to upload their .json files they go "main -> advancements -> main" but when i do it the folders are "fsc -> functions" and the .json files are in there, just saying in case that might have something to do with it, other than that everything is the same
