HELP Blockbench / Mcreator Animations

I have used animations tons of time in the past but with Mcreator 2026.1 I can't seem to make them work

I use mcreator 2026.1 ,Neoforge

I use Blockbench 5

So few questions

1. what do I have to use for my model in Blockbench: Bedrock Entity, Modded Entity, Geckolib entity, Optifine Entity ?

     2. what about entity model file exported from Blockbench: Java or Json ?

     3. what about animations instead: do I have to use Geckolib or not ?

     4. what about exported animation file: Java or Json ?

Please I really need help, I'm stucked
