Morph target of the 3D asset

Hello forum,
I have a 3D asset which is created by using avatar SDK API , now I want to apply facial movement on that 3D avatar using morph target feature of the babylonjs , and In the Babylonjs inspector i can see all the morph target value associated with that 3D asset, but I am unable to access that morph target inside the code. so please tell me how to access that morph target value inside the code.
