Issues with Calling the MergeCoplanarFaces Method

I’ve encountered an issue while working with compute.rhino3d. When I call the MergeCoplanarFaces method, the result only returns a Boolean value. I expected it to modify the number of faces in the input Brep, similar to how it works in ghpython, but nothing changed in the result. Could this be due to incorrect input parameters, or is it a limitation of compute.rhino3d itself? Any help would be appreciated. The code and partial results screenshots are provided below.

    encode_brep_data = cr3b.CreateOffsetBrep(folded_surf, thick * -1, True, True, 0.001)[0][0]
    folded_brep = r3.CommonObject.Decode(encode_brep_data)
    tuple_data = cr3b.MergeCoplanarFaces(folded_brep, 0.001)
