So the Minimap and Worldmap mod allows a top-down view of the area you are in/the area you explored with the mod.
The Mod would be compatible with waypoints.
The way you could implement it into the mod menu is to call it "Map" and inside of "Map" you can toggle the Minimap and the Worldmap as well as change the keybind to open the Worldmap.
What about servers that don't allow Minimap mods like Hypixel? Then do what you did to freelook on Hypixel where you disabled people from using it on the server
The images show what it could look like using an existing Forge/Fabric Mod
