I want to switch from basic automation to custom workflows 

For example, on the basic automation, I left a Jira .txt file in the comments

And I saw the on the intercom:
1. link to jira issue
2. comment 
3. .txt file
 

How can I set up custom automation so that it works the same for me as for basic?
 

Because the standard template cannot display a .txt file and .jpg file on the intercom.​​​​​​​
