In a sheet I have a column to enter a datetime value that would later be checked by a script to create a trigger.
I would like to set a picker in that column to ease selection and avoid errors.
I know Google Sheets offers an option in Data Validation for date but not for time neither datetime.
However, I found this class in the Google Apps Script API
But I just do not know how to implement it in a sheet (e.g. with OnEdit() or SetDataValidation()) so any time I press enter any cell in that column the picker is called to select datetime and set cell value to that selection.
