AWS CodeStar Notifications TargetType Chatbot Slack Channel

AWSChatbotSlack

That's the value to supply for the TargetType parameter when creating an AWS CodeStar notification when you want to target an AWS Chatbot Slack channel.

AWSChatbotSlack

I don't know why, but this is not listed anywhere in their docs. In fact, a Google search for "AWSChatbotSlack" shows the only place on the entire internet this is mentioned was in an example response on this somewhat-but-not-really related docs page.

Edit: AWS has updated their docs to include this TargetType.
