Reviving the Nerdy's Geckolib Plugin

I am working on the Nerdy's Geckolib plugin for 2025.3 EAP, I hate MCreators model and animation system. they could've done better however the new way to animate in Blockbench because of it sucks! i have already updated the Nerdy's geckolib plugins NeoForged generator to 1.21.8 and the geckolib api to 5.2.2 and the MCreator version to the 2025.3 EAP it loads and recompiles successfully. I just need some help with some UI Elements like geting the geckolib tab at the top to show so i can import the animations and models.
