Mesh offset edge

HI,

How can I remove an” ADD on” in blender removed the .py file and it is still there.

Working with blender 2.9x and I downloaded Mesh offset edges, it came with a warning explanation mark and I have to update to a2.8 version.

Try to remove it and try to find a version that work with blender 2.9 , can not find it. The Bombaba/mesh_offset in Github does not work with blender 2.9
