I'm admin on the Fabric workspace containing the mirrored db that corresponds to the landing page. In the Azure app registration, I've confirmed that the API permissions for Azure Storage as delegated and user impersonation is there, and granted admin consent for the tenant. In Power BI admin portal, "Users can access data stored in OneLake with apps external to Fabric" is enabled for the entire organization.

Any clue what I'm missing?

I really can be an idiot. I was missing the step where you add the app as a contributor to the workspace.
