"Starting in version 90, Chrome’s address bar will use https:// by default, improving privacy and even loading speed for users visiting websites that support HTTPS. Chrome users who navigate to websites by manually typing a URL often don’t include “http://xn--ivg or “https://xn--ivg. For example, users often type “example.com” instead of “https://example.xn--com-9o0a in the address bar. In this case, if it was a user’s first visit to a website, Chrome would previously choose http:// as the default protocol1."
