How do I tab complete a command?

[Rgamer]

So, I have a code that teleports the player to different worlds, like: /server [pvp, survival or creative], but then if I type in "/server " it doesn't bring up the tab complete option, can someone fix that?

The server is hosted by minehut, so if there are any more plugins i need for this to work, please check if they exist in minehut before posting said code.

You can add custom plugins onto minehut servers. And you cannot tab complete normal added skript commands, I think there was a way to add them
