Want to send message in accordance with file or comment issue is blocked

[Елена Елена]

Hello all,

Now I created the message to Slack which informs me about that the issue is blocked I want to move forward.

I want to get message based on actions made.

1. If the issues is blocked by file - there is a message which contains the link to the file which blocks current issue

2. If there is no blocking file, but there is a comment about it (I think I can use {{issue.comments.last.body}}) - I get message with the last comment

3. If there is none of them I receive the current message

Please help me with advice how I can do it

Thanks
