Ask HN: Convert Google Calendar URL to iCal

I'm trying to stop using Google; the only service I currently use is the calendar because where I take classes, they provide a gcal URL[1] when you schedule. I could manually populate my calendar, but you know how lazy programmers are. So before developing my own solution, I would like to know if there is a better alternative. Thank you. 1 - https://calendar.google.com/calendar/u/0/r/eventedit?dates=20240717T190000Z/20240717T195000Z&text=English+Class&details=English+Class
