I don’t think apart from Search Rows with a filter with any column value that exists can list all rows. You can try Apps Script to send data to make.com webhook when there is a new row. you can define conditions as well. But it is very unlikely that make can’t detect new rows added.
Make sure you are following these things:
Check if there are any hidden empty rows? If exists, delete those!
I think Make only lists new rows which are added just after the last row fetched which contains the data. Make doesn’t catch new rows which are added after an empty row. So make sure you are not having any empty rows in between the new rows.
