MMM-GoogleCalendar stopped working "INVALID_GRANT"

nowayto

After a week I got “INVALID_GRANT” does the token expire every 7 days because my app is in “testing”?
In fact my “app” in not an app, is just an authorization token for my calendar so my question is, if I publish the app, does my calendar datas could become public?
And how much time will be the OAuth token duration?
Eventually, which are your advice to another type of calendar?
Honestly I don’t wann become slave for the calendar authentication.
Thanks

@nowayto there IS a published api process to update the authorization token

so the module would need to follow that

the default calendar module can read google ICS file
and broadcast that to other modules (no display if no position set)

like MMM-CalendarExt3 (and family) which shows a wall calendar view
and Journal which shows a list view
etc

@sdetweil Ok, so I set your standard calendar module with google ics url; it should read google events and broadcast to CalendarExt3.
I hope I understand your message well.
Using ICS instead of OAuth my question is: does it update automatically or I have to manually update it?
Can I add more than one calendar? If you, which is the correct formattation?
Is the configuration under here correct?

            calendars: [
              {
            url: "ht****lendar.google.com/MYURLCALENDAR.ics",
            fetchInterval: 7 * 24 * 60 * 60 * 1000,
            fade: "false",
            name: "MYCALENDARNAME", // <= RECOMMENDED to assign name
            color: "blue", // <= RECOMMENDED to assign color
            customEvents: [{keyword: 'Birthday', symbol: 'birthday-cake', color: 'Gold'},{keyword: 'Dinner', symbol: ' pizza-slice', color: 'red'}],
