It looks like those are the only ones supported by the tap right now, see the tap repo
https://github.com/singer-io/tap-amazon-sp for more details. You have a bunch of options depending on how you want to proceed:
1. Build a new tap using the SDK with more stream coverage
2. Open an issue/PR to that singer-io repo to add more streams
3. Fork that repo and add streams similar to this one
https://github.com/atidivhq/tap-amazon-sp
I also see
this tap that has a ton of streams but it labeled as "Old" with a link to a private or deleted repo so I wouldnt necessarily recommend it
