How to get Amazon iso week number using custom formaating

Hi Team,

I want to display AMAZON ISO week number starting from Sunday to saturday. “gggg-ww” is not giving right week number. This week is 44 according to amazon but “gggg-ww” is giving 2021-43.


QuickSight uses this library for formatting Moment.js | Docs
If you need to get ISO week, then use upper case “WW” instead of “ww”.
