Proxy Geometry Tool not showing up 4.20

hi

any help appreciated - i follow docs to enable the proxy plugin as below, but i dont get the “ProxyLODMeshReduction” option, the only options are SimplygonmeshReduction or go to marketplace.

“Once the Project Settings is open, go to Editor < Hierarchical LOD Mesh Simplification and under the General section click on the Hierarchical LOD Mesh Reduction Plugin and then select the ProxyLODMeshReduction plugin.”

Proxy LOD plugin is enabled

Any ideas?thx
