How to get MANIFOLD_SOLID_BREP entity name in reading STEP file.

Hi,
Now, I want to get MANIFOLD_SOLID_BREP entity name.

First, I am reading the step file by OCCT.js and get Vertex coordinates, Solid/Vertex/Face/Edge Quantity and Solid start and end faces;

Second, I directly open the STEP text file data and know MANIFOLD_SOLID_BREP entity name exists in the STEP file. But I can’t read to MANIFOLD_SOLID_BREP by code.

Last, I hope to get the corresponding MANIFOLD_SOLID_BREP name when traversing to this Solid, like When I traverse to entity 1 and entity 2, I get the corresponding ‘Boss-Extrude1’ and ‘Boss-Extrude2’.

For Example:
