Connect Kopia UI to SFTP

I have managed to setup Kopia UI on my Windows 11 laptop but would like to use SFTP as repository but I’m stuck on Known hosts data?.
Where do I get this information?
Do I need to make a connection with Kopia CLI to get the known hosts data?

Perfect solution! Thank you very much. For older versions of Windows I can also recommend using cygwin.
Install cygwin and do a ssh connection with it. It will create a known_hosts file in /home/$username$/.ssh/ and just copy/paste the info from that file.
