installed everything muse node is nowhere to be found

[neom315]

I followed all instructions, downloaded all weights, all content of all folders, nothing to do.
if I try to import the demo workflow it doesn't show up at all, not even an error, if I go in custom nodes in the manager I see
only a "import failed" for the Comfyui-MusePose, the try to fix option ask to restart and doesn't do anything, if I try to simply add the musepose node, there is nothing.

I am running the latest version of comfyui with the latest versions of all nodes
