### Additional information

_No response_

Unfortunately commands are registered dynamically, so the client previews them as invalid.

it is possible to register commands while server working. Just add this feature to your plugin.

I don't think it's possible without touching Bukkit internal classes. Besides, the plugin is now in maintenance-only mode as I don't have the free time and passion I had some years ago.
