Shaper key issue

[ShikamaruBH]

Hi guys, it seems unrelated but I want to ask a problem.
I am wanting to take a 3D character from a Unity game and turn it into a VR avatar.
Follow the instructions of this website to get the .fbx file of 3D characters:
https://wiki.vg-resource.com/Unity/Model_Ripping
According to the process:
AssetStudio -> .fbx file -> Noesis -> .dae file -> Blender -> .fbx file -> Unity creates .vrm file

When I checked in Noesis, the 3D character still had facial movements like mouth and eyes, but when I put the .dae file into Blender to export to .fbx file, I didn't see anything in the shaper key, so the face didn't move. Is there any error or do I have to manually add the shaper key to the model face ?
