Marking Dates on the Calendar

If I have a list of days I would like to mark,

I wasn’t able to figure how to mark certain days.

Documentation is here: https://docs.dhtmlx.com/suite/calendar__api__calendar_mark_config.html

If I have a list of days:
[“2019-11-15T10:00:00Z”, “2019-11-16T15:00:00Z”, “2019-11-17T16:00:00Z”]

I want to highlight the 15, 16,17th of November.

Can’t get that to work at the moment.

Thanks

NOTE:

Figured out a solution.
