Fullcalendar show modal from url

I’m using Fullcalendar and everything is working fine, I have a weekly calendar with events and when I click on an event than a modal shows with more information about this event.

Let say I show this calendar from the url https://test.com/fullcalendar.php

I want to add some extra functions to this so that the modal of the event with ID 123 is showing when I go the to url https://test.com/fullcalendar.php?id=123, thus without clicking on the event in the calendar.

Is this possible?
