L2J Server

Hello,
I am working on a custom item that teleports the player wherever he wants with a delay.
However I can't seem to have my custom bypass work since I registered the class as a handler in datapack and the RequestBypassToServer class is obviously located in server.
My question might be dumb but would importing the handler (from the datapack) work in RequestBypassToServer.java (core) ?

You can make it work directly in the core, but I'd recommend investing more time to make it unhardcoded in the datapack.

Check item handlers, for example.
