Display only most recent comment in sharepoint list

I'm looking for a way to display the most recent comment in a Sharepoint list when the Comments are edited. I'm open to using a "comment" column with append text (like here: Find the most recent value from a multi-line text ... - Power Platform Community (microsoft.com)) or with the "comment" feature for a list item. I would assume there's a "most recent comment" column I would write the most recent comment to from either of these locations, but I can't seem to make the flow work. I'm pretty new to SharePoint and Power Automate and don't really have any kind of programming/coding background.

I've looked at the following too, but I can't make these do what I want.
