How can I do this? If I were able to rerender the routes without the React.renderComponent then I could add a update method in the routes file too. If you have other suggestions on how to solve this, they are welcome too :)

强制React 组件使用函数组件重新渲染函数组件不包括 forceUpdate() 方法。但是,仍然可以使用 useState() 或useReducer 钩子强制它们重新渲染。useState类似于类组件的 setState() 方法,只要更新后的 state 对象具有不同的值,useState() 钩子总是会触发更新。
正しく使用すると、React クラスコンポーネントの setState() メソッドを呼び出すと、常に再レンダリングがトリガーされます。shouldComponentUpdate() ライフサイクルには、この動作を防ぐ条件付きロジックが含まれている場合があります。
