Issue:RASA SLACK integration not working for direct messaging when @appName is given in slack_channel but #channel works when i add app in channel.

I saw that in NGROK UI i can see the response when i try direct messaging.

My event subscription settings are as mentioned in doc

When i use #channel in slack_channel it works as you can see in below screenshot

But when i use Direct messaging and use @Eribot in slack_channel i dont see response in slack, but can see response in ngrok

Hi @akelad , I believe this is not duplicate to issue #1415 as in that issue we are discussing about @mentions where we are not able to get the chat response when we refer to it using @mentions, So according to that app_mention is not working, but the issue i raised is for direct messaging when we refer to individual app using @app_name in credential.yml for slack_channel field. Here mentioning #channel name works but not with @appName.
Please correct me if i m wrong.
