A company uses Microsoft SharePoint document management in Dynamics 365 Sales to store contracts.

 Since the company uses Microsoft SharePoint for document storage, access to documents is controlled through SharePoint permissions rather than Dynamics 365 security roles.

 To restrict document access to only the contracts team, you should update the users list in the SharePoint site where the documents are stored. This involves configuring SharePoint permissions to ensure that only the contracts team (or a specific SharePoint group associated with them) has access to the document library where contracts are stored.
