how to get footprint type (smd, through hole)

Summary

I found this code in kicad source https://gitlab.com/kicad/code/kicad/-/blob/master/api/proto/board/board_types.proto#L774

enum FootprintMountingStyle
{
  FMS_UNKNOWN = 0;
  FMS_THROUGH_HOLE = 1;
  FMS_SMD = 2;
  FMS_UNSPECIFIED = 3;
}

message FootprintAttributes
{
  string description = 1;
  string keywords = 2;
  bool not_in_schematic = 3;
  bool exclude_from_position_files = 4;
  bool exclude_from_bill_of_materials = 5;
  bool exempt_from_courtyard_requirement = 6;
  bool do_not_populate = 7;
  FootprintMountingStyle mounting_style = 8;
}

but, I don't see any function for get mounting_style in KiCad API Python Bindings

Reproduction steps

and i try to use this code

#!/usr/bin/env python

import kipy

kicad = kipy.KiCad()
board = kicad.get_board()
footprints = board.get_footprints()

for footprint in footprints:
    print(f"Reference {footprint.reference_field.text.value}:")
    print(f"  Mounting Style: {footprint.attributes._proto.mounting_style}")

and all return 0 (FMS_UNKNOWN = 0), not FMS_SMD or FMS_THROUGH_HOLE:

Reference B10:
  Mounting Style: 0
Reference C128:
  Mounting Style: 0
Reference C84:
  Mounting Style: 0
Reference C96:
  Mounting Style: 0
Reference U8:
  Mounting Style: 0
Reference C147:
  Mounting Style: 0
Reference R115:
  Mounting Style: 0
Reference R112:
  Mounting Style: 0
Reference L7:
  Mounting Style: 0
