Books not bought non amazon

[fgionghi]

Hi, thank you for your work.
The only problem I have is that https://read.amazon.com/ does not show book that I didn't buy from Amazon, while the kindle app on android does and also https://www.amazon.com/kindle/reading/insights does show other books.

Do you think there is a way to get other books too?
Thank you

Hmm I think it might be possible to get the books but not the progress associated with them since I doubt that's stored on amazon servers. Requires some more digging
