Comment 36 for bug 1803604

Oh, not really well in Ubuntu 22.04.
Lo has sensible-lomua set in Email (don't know what's that, probably ends with xdg-email anyway) but behaves like when empty, invoking default mail which I set to be claws-mail. Also program window invoked, not composer window. xdg-email is 1.1.3-4.1. So that would be the same, not resolved.
Another new problem: if I set Email to /usr/bin/claws-mail, I get a message "LO unable to find a working mail configuration". claws-mail is version 4.0

If system has no default email client, sending with LO doesn't give any warning. That would be another issue, related to (3).
