Hubs/Multiworlds/Dimensions Forge 1.16.5

Relatively new to the MC Server development, running a Forge 1.16.5 server with Pixelmon and few other mods but I want to set up a hub and custom maps such as Johto that are able to be warped to via a command. I tried to do this via Forge Essentials but it conflicts with FTB Ranks and removed it due to it not achieving the result I needed. I have asked around alot of discords for support on how I am best to do this but no luck and blank stares hahah. If anyone could advise if I am going about this wrong or if they know a compatible mod that will let me achieve this I would be so grateful
