Question.... is this a custom styled menu, or can we use system menu?

I tweaked the style a little bit (more space, highlight based on our color palette). A good-enough V1 could be using native ones.

@alwx you can check for right click in touchable highlight with

[react/touchable-highlight {:on-press #(when (= "right" (.-button (.-nativeEvent %)))
                                            (utils/show-popup "" "Message copied to clipboard")
                                            (react/copy-to-clipboard text))}
 [react/text "hello"]]
