Amazon Seller Central test account / test mode / sandbox

Hi there,

My company uses AMTU to sync product information to Amazon Seller Central but as the application is reaching end of life by the end of the month, we are looking into using the Adobe Commerce Cloud (Magento) plugin to replace AMTU.

What we can’t figure out is how to test the ACC plugin without affecting our live stores on Amazon.
Is there a sandbox or a test mode to the Amazon Seller Central?

I can see sandbox for Amazon Pay but not for Seller Central itself. Many thanks and sorry if this has been answered in another topic.
