Thank you so much for this wonderful library! It's doing exactly what I was looking for.

• rctx-contextmenu version: "^1.3.7",
• node version: 18.8.0
• npm (or yarn) version: 1.22.19
• react version: 18.2.0

I just saw that it does not yet support StrictMode. I think the reason is the dependency react-transition-group that hasn't been updated since they removed their dependency on findDomNode which is the one throwing the error.
