CORS, WebDAV and CalDAV support

I spent about a week trying to understand how to get (non Nextcloud) WebDAV and CalDAV to communicate with Super Productivity in the web app so I could use it on mobile. There weren't very many good resources, so I wrote one that this community might find helpful:

Thank you very much for sharing this! I tweeted about it, though I don't have many followers ;) If you like to reach more people, I recommend posting it on dev.to, too. You can set the canonical url to the original, so search engines won't get angry, because of duplicated content.
