Glowing effect on armor?

Hi, I'm semi-new to MCreator (haven't used it in quite some time), and I've run into a problem. I can't seem to find out how to make a set of armor have the plain glowing effect (Make it look like it's enchanted.). I've tried adding custom code to the class, but it doesn't work, no matter what I do. Does anyone know what I could do to fix this?
