One solution my be startling an http server on esp32 and allow user to upload a screenshot of the QR code and decode it on esp32.

I do not see the benefits of implementing a lot of stuff. Why not using the USB connector?

some laptop simply does not have enough USB connector
also the phone USB port may not be able to supply the power for esp32
