Create a button that chooses dates by filter

[roxys373s]

Hello,

I'm trying to create a button that chooses the last five dates of all the dates included in my data. How can I do this? 

Someone else suggested that I do Date(Today()), but that chooses the last 5 days before today, rather than from the dates in the data.

I tried with the numeric date, it works okay, couldn't get it worked though with the date field yet.

Load *,Num(Date) as DateNum inline [
Date
01/01/2021
01/31/2021
02/15/2021
02/28/2021
03/10/2021
03/20/2021
04/01/2021
04/15/2021
05/10/2021
05/25/2021
];

Expression used in button action as - 

='($(=max(DateNum))|$(=max(DateNum,2))|$(=max(DateNum,3)))'
