Hello - the PRG-10 (the item here in the shop) looks like this: Albrecht PRG-10 programming cable, USB stick for radios
even if there (a wrong picture is shown) the Tectalk Worker 3 is not listed, the article number C974.01 matches the one from Albrecht, where the Worker 3 is mentioned again:

But, the software is also available for download: https://www.alan-electronics.de/artikeldet...
(on the right hand side under Downloads) ("Tectalk Worker 3 Software") - if that's it :) - The cable looks like a regular USB-C cable (USB-C to -C or USB-A to C), like the ones you have in reserve - it may well work already.

I would first try the "free" variant (download and USB-C cable from your own cable box)... and otherwise write to the customer service here (whether the C974.01 is really the right product -or- write to the service at Albrecht, whether it also works without a purchase item, with the download and your own USB-C cable).
