Display Modification Date if newer than Creation Date

I am also struggling with this one, however it doesn’t work as it should.
The outcome this is suppose to give is, whenever the field ( in this case; a comment ) is modified, it should show the text ‘edited’.

I have a record, which was created 11/11/2022, 14:02, which I later made modifications to it, at 11/11/2022, 14:04.
Using this method, doesn’t give me the outcome I want, which is the text ‘edited’ to show.

Any other insights ?
It should compare the created and modified date up to the seconds. Cause the field can change within days of being created, but also within seconds of being created.
