intersectsMesh witout showBoundingBox

I use the intersectsMesh method as in the Babylonjs documentation. If the second parameter is true according to the information described in the document, it will have to hit the mesh directly without hitting the boundingbox. I researched for many hours on this subject, but could not come to a conclusion. What I want is to find that only intersectsMesh hits the mesh. How can I find out if the round ball hits the tube, to take the example? Please your help.
