To enable state persistence, set stateStoring.enabled to true and specify the storageKey and type properties. Depending on the type, the state can be saved to a localStorage or sessionStorage. With localStorage, the state persists across browser sessions; with sessionStorage, it is reset after the current session. This demo uses localStorage.
Alternatively, you can implement the customSave and customLoad functions to save and load the state according to custom logic. In this case, set the type property to "custom".
