Whenever I try to add a Bedrock player to my whitelist by using /whitelist add *<playername> it always tells me that the player is not found. I assume that Geyser is installed on all servers by default since I can't find it through searching addons. Could someone tell me what I am doing wrong?

I have recently been attempting to upload a world file to my server, but it doesn't work. All videos I have found online are outdated and use the /world command. What I have been doing so far is taking the world's files and compressing them into a .zip. I then go into the world tab and upload the zip file. This is where it doesn't work. I have tried restarting the server but that didn't change anything. Could someone help me with this? Just to be clear I don't want to make a new world that can be accessed from an existing world, I simply want to delete the random world the server started with and replace it with my own.
