Usually the handling of luggage is not by air france (or other carrier), it is the specific airport personnel, so called "ground-services".

Most airports cut down personnel due to Covid-19 and when the amount of flights quickly ramped up to previous (or possibly higher than before) levels couldn't manage (or did not want) to find/hire/re-hire enough personnel.

When this happens, the luggage is normally stored in a hangar or other warehouse at the airport, far from passenger traffic, and with access reserved to these ground service personnel, so the most you would get with an airtag (if any of the personnel has an iPhone) is that your luggage still exists in a place which you cannot have access to, no way to collect it.
