Need setup help for Big Talker smartapp

I previously had BigTalker working fine. I removed it and added BigTalker2. Now I am having a problem. When I try to configure it, the Talk with is grayed out and says “You can’t currently add this.” What am I doing wrong?

What is BigTalker? Is it an official app?

I am not sure if it is official. It is a smart app that can be added via github.

No, it was created by a community developer.

Best bet for getting support is to post in the developer’s thread for the smartapp.
