Smartsheet calendar in google calendar for non-smartsheet users; changes not reflected
I'm trying to find a way to add a smartsheet calendar to my team's google calendar where if I make changes to the event dates on the smartsheet calendar, they would also be reflected in google calendar. If my team subscribes to the smartsheet calendar via URL, they don't see changes made after they've subscribed to it. My team does not have smartsheet licenses.
P.S. I can publish the ss calendar in my own google calendar, but don't see a way to do it for a broader team where changes to the calendar would be reflected for them.
