Minecraft RTX ON How does it work with the Java Edition?

A few years ago I bought Minecraft as a Java Edition so not in the Microsoft Store.

Now I wonder how I can activate RTX ON there without buying Minecraft again from the Microsoft Store

They are two different versions of Minecraft. Once you bad and the Java Edition

It does not work.

Moin but it works I got it now

In itself you can't activate RTX, BUT you can download shaders for which you need the OptiFine modification, these shaders use RayTracing (what you probably want)
