The poser uses the humanoid skeleton bones as set per the vrm's avatar component. If your model is custom made the avatar may not have been set correctly when it was converted to the vrm format. I would ask your modeler to have it re-exported. Either way, you can use any model inside the poser and you should be able to receive the tracking data in VSeeFace with whatever model you have loaded in
