For instance, if you already exported a component, and you want to add a new text field and button, you do that in Figma, use Quest plugin to "Sync Component" and then in Quest, you set up props/bindings for the new text and button, then export the Component or export the App. Once exported, replace the component file BUT don't replace the logic file you already have logic in, just add the additional parts you added to the original file. So if component were called "Card" you'd export it and replace the "Card.js" and merge the "useCard.js" file. No need to start from scratch with a new component, just always Sync the component you're updating back to Quest.
