Approximating any geometry to standard NURBS form

It was mentioned in the Hoops Exchange documentation that “You can additionally ask HOOPS Exchange to approximate any specific geometry and provide it in a standard NURBS form” in Parasolid Reader. Also attaching the link here
(Parasolid Reader — HOOPS Exchange Documentation)

Is this compatible only for Parasolid files or even for other formats? If yes, how can I ask Hoops Exchange to provide it in standard Nurbs form?

If anyone worked on it before, eagerly waiting for the help!
