Give Zenity foreground on macOS

Zenity-mac.bash

#!/usr/bin/env bash

zenity --password &
zenity_pid=$!
osascript<<EOF
tell application "System Events"
    set processList to every process whose unix id is $zenity_pid
    repeat with proc in processList
        set the frontmost of proc to true
    end repeat
end tell
EOF
# Can't use fg by default, that's for interactive shells.
# But this waits for all background processes to finish.
wait

Probably can achieve everything through just the osascript command without all the GTK stuff anyway. This project is one example but all this could be rolled in shell/etc. plus osascript.
