How do I apply shaders in Minecraft?

I planned to use a shader in Minecraft that I have already installed. I then watched videos to see how you can use the shader in Minecraft and under which settings you have to look. But I noticed that in every video the interface was different from mine… In every video the people had the same settings in the interface, only mine are a little different. They all say you should go to the graphics settings, but for me they look completely different and I can't find an area for shaders.

I have the normal Minecraft (not cracked) and got it for 30 euro from the Microsoft Store and play on the latest version 1.16

But where can I find the shader settings and why does it look different for me?

You have the Bedrock Edition. For shaders you need the "right" Java Edition from minecraft.net. You also need OptiFine.

You have the bedrock edition the actual console edition correctly use shader and other things only work in the Java version
