I followed these instructions for importing my Google Calendar into Outlook 2019 as an "Internet Calendar". The calendar now shows up in Outlook under "My Calendars", and if I accept a meeting request from an Outlook email then the meeting gets added as an event in the Outlook calendar. However, if I try to manually add my own event to the calendar, it errors saying that it's read-only:
Similarly, if I edit an existing event (added from an email meeting request) and try to change anything such as setting a reminder, it gives another error about reminders not being supported and asking if it's OK (it's not OK…)
What do I need to do to get my Google Calendar syncing properly with Outlook, so that I can add and make changes to events?

As described in the article, the imported calendar is a static snapshot.
If you subscribe to it, to update your Google calendar, we need to open Google Calendar from a browser.
Do you use Exchange account in Outlook? As far as I know, Exchange account will sync calendar items as well as emails or contacts with server. If yes, you can import Google Calendar to your existing account in Outlook client and then directly use your new calendar as a replacement.
