Icon on gamemode?

Hey guys so I have been working on a gamemode for the last few weeks and recently I made an icon and logo for it. The problem is that I have the icon and logo in the gamemode folder but they don’t appear in the server browser when I go to my server. Any ideas?

Do they appear on the singleplayer tab/button

Do you mean in the start new game button/tab?

Down the bottom right where you change gamemodes.

Oh no it’s not. I have it set up on a dedicated server if that helps.
