I can find the element with CSS path `html body.sidebar-open div#reader-ui div.split-view div.primary div.view-popup.selection-popup.page-popup-bottom` in Inspector, but I want to get it from the Zotero object.
Methods I have tried but failed:
1. click Use in Console and get a object named temp0, but I don't know what the top most html parentelement is obtained by `temp0.parentElement.parentElement.parentElement.parentElement.parentElement`
2. I thought it would be `ZoteroPanel` or `Zotero.Reader.getByTabID(currentId)`, but they are not
Could anyone please tell me how to get the selection-popup element in script?
