1. How to display a mask in the Phone Number component. eg: if i pass default country and format, how can i display mask in the component. I tried but i couldn't show the mask.
2. In future, in the storybook(https://react-international-phone-storybook.vercel.app/?path=/story/phoneinput--default) , please add another variant to show a default mask.
