Images are not automatically translated from HEIC to JPG on import

I have in my iPhone a mixture of HEIC and JPG pictures. I have set my "Photo" settings for the transfer of pictures to a Mac or PC to "automatic". From my understanding, this should convert the pictures from HEIC to JPG on download via cable (I conclude this from [What is HEIC file, and how to convert HEIC to JPG?](https://macpaw.com/how-to/what-is-heic-file) , paragraph "How to transfer iPhone photos as JPG, not HEIC"). On my MacBook, I use ImageCapture to transfer the files. However, the HEIC files end up as HEIC. No conversion to JPG is done. What did I do wrong? Version information: iPhone 14 Pro Max, iOS 16.6.1 MacBook Pro, MacOS 12.6.9 Image Capture 8.0 **UPDATE** [Export media from iPhone directly to external drive?](https://apple.stackexchange.com/a/465517/85275) claims that the conversion can be controlled by Image Capture. This does not seem to be true for my version of Image Capture, which does not have a "Keep Original" option, as can be seen from the screenshot:
