Using OcclusionSubGraph in another Subgraph stopped working with 72.0.0

Hi, as title says, it does not seem possible anymore to use the provided Subgraph for Occlusion in another Subgraph. Not sure what the reason might be, probably somewhere in the includes. It worked fine before (we were on 69.0.0 before).

On another note, is this forum the right place to ask such questions? Because I never saw any interaction with Meta Devs, only generic bot answers, which does not make any sense in a Dev focused forum, at least not with this kind of generic bot. Is there another place to file bugs for Meta software?
