Question mouth animation not working

I'm having problems with animation regarding the mouth. I made an animation in blender and the whole body works normally, but the mouth doesn't move in the game. When I put it in the game, the mouth doesn't move, I've tried changing the jaw, but it didn't work. The model I used was from Daz3D, I put it in blender and made the animation manually and imported it into unity. When viewing the image in the inspector, the mouth moves normally, but when I put it in the game, the mouth stops moving.
