Extracting Plotly 3d Volume as an Object

I am using the Python Plotly volume function to develop a volume plot surrounding a point scatter. The area around each scatter point is shaped by a Gaussian filter around each point, with the result shown below.

For further analysis of point density in our data at high resolution, I am planning on docking spheres of constant volumes inside the 3D plotly volume shown here. I was wondering if it is possible to extract the coordinates and shape of the generated contour as an object, which I could then use as the boundary for the sphere placement.

Unfortunately you cannot extract the coordinates, because they are calculated by plotly.js, and there is only one direction of data transmission (communication): from plotly.py to plotly.js.
