Formula to filter between two dates a table with a segment

Hello,

Thanks to my two tables (Contract start date and Contract end date), from a hierarchy of dates (which is my segment which filters the entire page), I would be able to filter the users who are present at the within a society.

I thought about creating a filter to select all users with a contract start date <= on the filter and all users with a contract end date> on the filter.

If you also have an idea to change my segment on the page: a hierarchy from date to calendar because I haven't found.

Can you help me with the formula please?

Cordially.
