Uploading a world in 1.18?

[febreezle]

I know how I'm supposed to take the world file, make it into a .zip folder, and upload it in the World tab on my server, but whenever I do this nothing happens. I've tried to look at past tutorials, and they mention a 50mb limit, but that you can upload larger worlds ingame. However, the commands these tutorials tell me to use seem to not be available anymore. Is there anything I can do about this or is it just some kinks that have to be ironed out with 1.18 first?

If I remember right there toke down the world up and downloads . 
you're able to download it with Minecraft helper plug-in on market but you can't upload any worlds
