As said in the subject, every time I add a to-do in Reminders.app from the Safari 'share' button, it gets created as Chrome Link, rather than Safari. Therefore when I click on it, it opens Chrome.
I have checked and Safari is correctly set as default browser in preferences, and in the Reminders.app preferences there's nothing related to browser.
For Reminders.app I mean the native macOS application.
If I do the same action on iOS, the link is correctly added as a Safari link, and trough the iCloud I get the to-do as Safari link as well. So it is something that macOS is doing.
Also, I have exported the to-do list and opened with text edit:
This is the to-do from iOS, which works fine:

This is instead the to-do added from macOS, as you can see there is a whole new section
