Aha, that is easier, thanks. GLib.Bytes.new_from_bytes doesn't seem to be
used correctly - it takes at least an offset and a length parameter? What
you want in this case, I think, is a ByteArray. See the documentation here:
https://github.com/GNOME/gjs/blob/master/doc/ByteArray.md

GJS console is just an executable ("/usr/bin/gjs") with which you can
execute a GJS script directly.
