How to make an animation looped in geckolib

I'm making an animated block using Nerdy's GeckoLib Plugin, in blockbench I set an animations Loop Mode to Loop, and it doesn't seem to work in-game, the animation ends and doesn't loop. And I've tried making a solution but it didn't work and it was hacky, I don't know if I set it up correctly, or if the animation loop mode doesn't carry out in-game.
