How do I retrieve data with Plasmo storage api

  const [selectedDeck, setSelectedDeck] = useStorage("selectedDeck", null)
...
setSelectedDeck(deck)

class MediumHighlighter extends HTMLElement {
  ...
  async highlightSelection() {
    ...
    const selectedDeck: any = await storage.get("selectedDeck") 
    console.log("selectedDeck: " + selectedDeck)
    ...
  }
}
