Wowza Streaming Engine

Hi all

I tried to implement text chat at Wowza, but didn’t get any result.

I followed the link :

https://www.wowza.com/docs/wowza-media-server-additional-examples

But while running textChat example it showing a message:

This application type is not supported by Wowza Streaming Engine Manager.

PLease let me know the right way to implement it.
