How to set up the screen not to light on when Viber message is received?

[Windows Central Question]

I have a Lumia 640 SS LTE and installed viber. When message is received, the screen lights on, but I don't want that, just the sound is enough. I could turn it off on my previous Android phone, but there isn't that option on this one. At least I couldn't find it. Can someone please help me?

Go to Settings >> Notifications + Actions >> find Viber from the list >> Turn-off notification banners
