Hi,
Extensions cannot be used in interfaces. Therefore, the Map extension can only be access in Data mode (at the table level).
Furthermore, any kind of filtering done in interfaces will only ever live in interfaces.
You will have to use a third-party tool, if you want to create a public interface that updates a map. I can't think of a solution that offers this, but it would be possible to create a custom application that uses the Airtable API to create filters and read the date
