What is the "Force secure connections" option used for?

In the WordPress Admin (5.9) there is a Https Setting under the general Tab. This seems to be very new, as it is not translated to my native (german) language. Furthermore it says:

HTTPS is essential to securing your WordPress site, we strongly suggest upgrading to it. More details

  • [ ] Force secure connections

The link is broken, this seems to be the new one. However there is no information about what this option is used for. Is it for HSTS maybe? But what if my webserver already enables that? The security headers check at least tells me so.

Any ideas?
