Shortcodes Issues 2nd

I’d like to have a shortcode, where I can use it for android and ios. The suggested webcal and ical links are not working for both. So it would be great to have this solved in one. As I have seen, not many plugins do have this solved.

There is a render platform https://decomaan.github.io/google-calendar-link-generator/, but since I need to unescape everything, I can’t use it.

This would be a big feature request from my side and a big advantage for you :-).
