Thank you for reaching out. Based on the use case explained you can create a new access review for the specific application.
While creating the access review you may also choose to configure Enable review decision helpers if you would like to receive recommendations during the review process.
If you select No sign-in within 30 days, users who have signed in during the previous 30-day period are recommended for approval. Users who haven't signed in during the past 30 days are recommended for denial.
As you would be creating an access review based on applications, your recommendations are based on the 30-day interval period depending on when the user last signed in to the application rather than the tenant.
For detailed steps on creating an access review please follow the below documentation.
