The feature that the app builder should use to create easy access to the document is a custom detail page link on the Contract object.

Sharing the dashboard folder with roles and subordinates of the US Sales Director and sharing the report folder with the role of US Sales Director will ensure that only the US sales directors can see the data in the component and view its source report, while all US sales reps can view the US Team dashboard. Making the US Sales Director the running user will show only his or her data in the component, not the whole team's data. Making the dashboard dynamic will show different data depending on who is viewing it, not based on their role. Sharing the dashboard with the public group US Sales Reps and sharing the dashboard source reports folder with the US Sales Director profile will not prevent other profiles from accessing the reports if they have access to the report folder.
