An alternate Bungee command without enabling /server
The following is a unique use case: Not using bungee's /server permissions for players If you wish to disable the Bungee's /server command but still allow users to switch between a select whitelisted amount of servers you can. This helps so staff can use /server anywhere but require players to use /join only where configured to go.
Specify the custom command you want for this function on this server instance. In this case, /join specifies this function with the "join" string. Do not include the "/" character as this is already handled in the backend
These are a group of servers that you want the /join command to have access too. In the above example, ogskyblock would be the argument the user would run. (The can see this when running /join). From here the bungee would send them to the "OGSB_HIDDEN".
