Please help

Hi. Im trying to do my own animated mob in 1.16.5 forge. So i needed Geckolib. I have loaded 2024.4 mcreator and correct version of geckolib and generator for 1.16.5 forge. But there is a problem. I just cant to create "Animated Entity" in 1.16.5 forge. If i try to make it on original minecraft version of mcreator it works. But with forge generator there isnt.. Animated entity doesnt support. BUT I tried a lot of differnce versions of mcreator and plugins. Its always doesnt support. Some people are using Geckolib in 1.16.5 forge. Cause of this im sure there is a way to find a way. Is somebody does know what should I do please tell me.
