How can I receive the current displayed week of google calendar with app-script?

Question

I cannot find any property receiving the currently for the user displayed calendar week with google apps-script here

What I want to do is: Extract the start and end date of the days displayed for the user in google-calendar.

What I already archive is to get events of the current week's Monday (so from the perspective of today):

getEventsOfThisWeek(calendarId) {
    calendar = CalendarApp.getCalendarById(calendarId);
    let referenceDay = new Date(); //here I would like to get a day from displayed week 
    let monday = this.getMondayMidnightAM(referenceDay);
    let friday = theís.getFridayMidnightPM(referenceDay)
    let events = calendar.getEvents(monday, friday );

    return events
}


getMondayMidnightAM(ref) {
    let day = ref.getDay();

    let diff = ref.getDate() - day + (day == 0 ? -6 : 1); // adjust when day is sunday

    ref.setDate(diff);
    let mondayMidnight = new Date(ref.toISOString().replace(/T\S{8}/, "T00:00:00"));
    return mondayMidnight;
}

So far I understood, that isSelected() tells me not if the event is on screen in the current view, but rather if the display in all the calendar option is on.

In Short: It is not possible.

• The problem with the calendar page you see as a user is that if multiple users have access to the same (e.g. group) calendar, every user might look at at different week.
• The script can only access server-side data that is the same for every user (e.g. event name, guests etc.).
• Only an Addon can access some specific information that only the user who installed the Addon sees.
• This information is contained in object events that become available when a manifest or contextual trigger get fired - e.g. when a user creates or edits an event
• However, as you can see in the documentation the Calendar Event Objects do not comprise any information about the currently open week, so there is no way to get this information programamtically
• Maybe it is possible to get this data through webscraping, whereby I would not be able to tell you if and how this can be done
