How to create an emissive/glowing block texture?

Hello, I created a block (a monitor) for 1.20.1 and I want only the screen to glow/emit light. For the screen I created an emissive material in blockbench, in the preview it looks perfect. But when testing it in mcreator the screen doesn't glow. Is there a way to do it without additional APIs?

check the "enable emissive rendering (glow)" checkbox in the block mod element in mcreator, it's in mcreator not blockbench

this will make the entire block (all faces) emissive but if you want to make a single face emissive you need to edit the json file of the block model to add light_emission:15 or whatever

So I found a way to do with shaders:

I created a specular texture for the part I wanted to glow. For the shader to recognize it, I named it like the texture for the part I wanted to glow but added '_s'. Now only the monitor glows :)
