In your server settings, go to > Worlds. There you see your current worlds on the server. Next to it you will find "Upload" and "Generate". Your world must be in a folder or ZIP folder. After that you upload it at "Upload". If you want to create a world with a seed, use "Generate" and enter your seed!

bro my map is bedwars i uploaded and when i go in game and typed where i added that map by tping /mv tp world and when i entered it was full black

Remember to note the coordinate of the map (see the coordinate of the map in Singleplayer), and teleport to there. Then do /mv setspawn.

i will try this out
