Hi,
I am looking for a solution or ideas on how to add week numbers to the H5 Date Picker in New UI.

In Classic UI we have been using the H5AddWeekNumberToCalendar script from this post:
(+) Adding Week Numbers to H5 Date Picker - H5 Scripting - M3 - Customer & Partner Community - Infor Community
but it does not work with the new UI.
Does anyone have an idea on how to make a similar solution for New UI?
The only thing I can think of would be to manually add a new table column with the week numbers, but I am not sure how to attach event listeners for when the calendar is displayed and when the month is changing.
Thank you,
Rene`
