How to turn off Viber's new SMS income message notification I am getting double SMS notification, i.e. one from system SMS app and another one from Viber. I don't want Viber SMS notification and need to turn it off.

I'm looking in Viber app's setting but I cannot find where to turn it off. All I can find is the below snapshot; but I guess it helps to reply the SMS message via Viber text message and save my mobile fee. I don't want the notification though!

Any work around for this please? Great appreciate.
Go to viber, in the bottom corner you should see 3 lines stacked on top of one another (Menu) click on it, then click on Settings, then on Calls and Messages, and you should find that option.
