So for my mostly non-tech understanding, will we be able to ‘Add to Home Screen’ and have nostrnests.com function like an app?

For example I did that with timechaincalendar.com by nostr:npub1jdgclywl55wc4neey97de57jenghsseuh8njx6z5f2kdwsfvk5xqhd2mys , but he did mention that he had to optimize for that to work.. Not sure if that would work with a site like nostrnests where people and creating/joining/leaving etc..
