Dont worry. The hunts are very easy going. You can just show up and follow the group, and you can leave whenever you like. You dont have to do anything really, other than keep up with the group. So my advice is to try it. Best case you can help with the hunt, worse case you get some loot.
If and when you feel like it, you can join on discord. I dont speak there because I have a daughter who is sleeping in the next room, but it if good for listening too. Like “watch out for the holes / lava ahead”, “we are going north” etc.
If you need to leave the computer (like you said you might have to) you could befriend one of the players in the hunt. Then you can warp to that player when you get back and resume, if the hunt is still on.
