swift , load model function can't play animation but load function I can play

Question

 let me=try! ModelEntity.load(named: filename)
        print("count is \(me.availableAnimations.count)" )

        
        
        print("\(me.availableAnimations.count) model animation number model entity is ")

above is that I use load function, but availableAnimations.count is 1 so I can play

let me=try! ModelEntity.loadModel(named: filename)

        print("\(me.availableAnimations.count) model animation number model entity is")

but with loadModel function, availableAnimations.count is 0 so I can't play animation

is it possible for me to play animation with loadModel function?

Thank you!
