Jira automation: can I include an image from a custom rich text field in the message sent to Slack?

[Karl Becker]

I have an automation rule setup to send a Slack message in certain criteria.  

The Slack message contains information from a custom field that allows rich text, including bolding, italics, and embedding images.  

However, when I add an image to that field, the Slack message contains a reference to the file name, but not the image itself embedded into Slack:

Is there any way to get the image to appear here in Slack?

Thanks!
