How to set glb or gltf model to certain direction in scene

[yicong123456]

I used gltfio to load model and wanna add the instance created by asset(load from model) to a specific position(a dynamic position) in scene. May I know if I can achieve that make the instance always toward to y axis(or have specific diff from y axis). I tried use transformManager to do rotation but it seems that for the same instance I add to scene, I need use different transformMatrix to transform it towards Y axis in different conditions(different data source form backend, but I am confused that the only data I need is the position(x, y, z), why it have influence on the rotation information). I suppose it should be only one transform Matrix to rotation it the certain angle in y axis because I think the initial rotation status should be same as I loaded the same glb or gltf to get the FilamentInstance to render. May I know if I miss any steps to achieve this goal and thanks so much!
