SharePoint List - Multiple Line - Append Changes to Existing Text - View Entries

I do not know how to help you with this other than maybe use the 'comments' feature (the little bubble slightly to the left of 'Lucky' in the highlighted list item of your screenshot).

I'm actually exploring a search issue with the multiple lines of text field and the append changes setting enabled. It is not showing in search results at all. I think it has something to do with that field actually showing 'View Entries' and/or it being a 'classic' setting and not modern. Anyway, planning to 'reindex' the list but probably moot since I can't manually 'Index' multiple lines of text anyway! I have a second multi-line column in my list that does not have append changes. It does show in search results although it's poor. Probably a separate issue but the poor result example goes something like this:

item contains the word 'repaint' in non-append field and 'paint' in append field. When searching 'paint' it doesn't display at all in results. When searching 'repaint' it displays in search results properly.
