[GeckoLib] How to play an item animation on key press?

So I made a 3D model of a gun in Blockbench with GeckoLib, added a reload animation, imported everything to Mcreator and the model and the animation work, but I can't figure out how to make the animation play when the player is pressing a keybind. I made a procedure for a keybind(on the screenshot), but when I press the keybind nothing happens and the animation doesn't work. What am I doing wrong?
