Not able to see the volume of staircase model from revit

I have uploaded a Revit structural model to Speckle that includes a staircase. While the staircase volume is visible in Revit under the Material Volume


parameter, I am unable to locate this information in Speckle.

I have checked all available properties in Speckle but could not find the volume parameter for the staircase. Could someone please guide me on where to find or how to access the staircase volume in Speckle?

Also i am getting this popup as shown in picture.

Does Revit itself give a material volume for this stair in app?

Yes the revit is showing material volume while its not visible in speckle
