When using RVD, how can I split the input surface mesh edges and the clipped bisectors in the final output mesh?

It seems that when I use compute_RVD_cells or RVD->compute_RVD(M_out), the surface mesh edges will merge to the final output mesh. But can I only get the intersectrion between the bisectors and the intersection between the bisector and the surface(excluding the original mesh edges)?

I found the same questions in another mirror repo, but cannot find the answer online. The link is attached below.
