RealityView in swiftUI look weird on vision pro

it is way above of control panel.... the code I show usdz modeling is as below

`RealityView{ content in let entity = try! await Entity(named: "idle") entity.setScale([0.15,0.15,0.15], relativeTo: entity)

        // Enable interactions on the entity.
        entity.components.set(InputTargetComponent())
        entity.components.set(CollisionComponent(shapes: [.generateBox(size: [2,2,2])] ) )
        content.add(entity )
        
        
    }`
