GNOME Shell integration problem

["Juan R. de Silva" <juan.r.d.silva@gmail.com>]

Hi folks,

I'm running Debian Stretch with chrome-gnome-shell installed. GNOME Shell 
integration add-on works just fine with Firefox but does not work with any of
Chrome based browsers (Vivaldi, Opera) and Google Chrome itself. It
throughs message "Although GNOME Shell integration extension is running, 
native host connector is not detected. Refer documentation for 
instructions about installing connector."

Googled for about 1 hour in vain. Actually found a couple opposite
complains on Although GNOME Shell integration not working with Firefox
while working with Google Chrome.

Can anybody help with the trouble, please?

Thanks
