removing items.padding was a result of seeing that it is not in the ApexOptions type. From what I can see in the chart, removing it had no visual impact either. Lastly, it is not in the docs: https://apexcharts.com/docs/options/tooltip/#items
so it seemed safe to remove along with using the return type
