What is the Privilege to get access for Analysis read only OTBI

Hi Team,

We have created a custom role with Project-related OTBI Duty roles, and along with that we added the BI Consumer role. However, this does not provide the Analysis option. When we add the BI Author role, the Analysis option becomes available, but it grants full access.

Our requirement is to provide view-only access restricted to Project-related Duty roles. Could you please confirm if there is any specific privilege or restriction available to achieve this?
