Is there an Access Management document that shows access permission at architecture level?

Hello, I am looking for a Access Management whitepaper or similar document where I could understand the way the architecture of access and permissions in the Qualtrics platform. I have reviewed the support and how-to materials from the support page, but this just tells how to setup, it does not give an overarching view. https://www.qualtrics.com/support/survey-platform/sp-administration/managing-users/creating-and-managing-users/ or https://www.qualtrics.com/support/survey-platform/sp-administration/managing-users/user-permissions/#GeneralPermissions Thank you
