in execution of iwctl without sudo. But when I tried to search that, It has low information in google but I solve the issue as executing with sudo. So this is very small change but this will improve this software.

ps. I get issue in linux kernel 5.16 and later, including 5.17.x

This is actually result of removing 'at_console' from the dbus configuration which we did a couple releases ago. The fix here is to add your user to the netdev group if you don't want to run with root. I'm not sure we want this debug print as-is for a few reasons. First being that it should explain the netdev group requirement rather than 'root permission'. And second that this could be an error for any number of reasons, not necissarily because of permissions.
