Adding External Extension / Motion Planing extensions are not working in Isaac Sim

Omniverse Isaac Sim

Hi,

I am trying to use already developed extensions for path planning for my wheeled robot but all the extensions provided/added by third parties or Nvidia in the Isaac Sim are not working, could you please guide how I can use LULA algorithms for my wheeled robot path planning?
