Pipeline checking if file attachment has changed

Question

When a record changes (trigger) I want to be able to tell if a specific file attachment has changed. With most fields I can compare the field {{a.name}} with the previous value {{a.$prev.name}} to detect a change in that specific field. This does not seem to work with file attachmenty field types. Is there a different syntax?

Try making a formula text field called [File Name]
with a formula field of

ToText([Name])

where I presume that [Name] is your file attachment field.

Then try prev in that.
