I appreciate you posting your concern here in the Community, Rah.
Let me offer you an alternative way to ensure that your donor can access project reports without seeing other project details in QuickBooks Online Advanced (QBOA).
Please note that currently, QuickBooks does not support granting access to specific projects or customer reports without revealing other project details.
While you can assign your donor the View company reports role in the Manage users page, this will give your donor full access to the Custom, Management, Expense, and Sales reports. This goes against your intentions because this role includes reports that are not related to your requirements.
As a workaround, you can consider exporting or emailing the report directly to your donor, allowing them to view it at their convenience. I'd be glad to show you how.
Additionally, with the export option, you can choose to export the report to Excel or PDF by clicking the export dropdown arrow.

You have my attention in case you have further questions about access roles and reports in QuickBooks. Keeping you in working order is my top priority.
