HELP: Blockbench can't export JAVA?

I'll cut it short; I'm trying to make animations for my newly created custom mobs. I'm using Geckolib in Blockbench, but can only animate in a Geckolib Animated Model Project. Thing is; I can't export that model to JAVA, which means that I can't import it to MCreator. I've watched tons of tutorials online, and everyone's able to export the model as an "Animated Java Entity".

I don't know if I got the wrong software, or if the newer versions of Geckolib/Blockbench doesn't have these supported features. But I wanted to reach out here to see if anyone knows what the problem is, and if so, how I can fix it.
