Viber - change color of buttons

What is the way to change color of buttons on Viber channel? Thanks!

@PavolD To change/set Viber buttons’ color, the color has to be passed from the Bot Training data. This feature, however, is supported in Hybrid Chat v3.11 and not before that.

Great! On the last session we had you mentioned that 3.11 will be available by September 28th. Shall we expect it today/tomorrow?

The release is available now http://docs.expertflow.com/chat/latest/release-notes
