Greate sample ! There is one error – in CORS screenshot delete „/“ after url of function.

Have you attempted to extend your example to secure the Azure Functions using AAD authentication? I.e., do you know how to adapt the configuration for an Angular app hosted on Azure Storage as a static website interacting with AAD-secured AZ Functions? Supposedly, the MSAL-Angular library can accommodate this scenario. https://github.com/AzureAD/microsoft-authentication-library-for-js/blob/dev/lib/msal-angular/README.md.

One issue that still exists is that you cannot add a secure custom domain, which makes this service less useful. You get a cert mismatch error when trying to do so. MS does document this at https://docs.microsoft.com/en-us/azure/storage/blobs/storage-custom-domain-name and suggests using their CDN service. Which comes at additional cost and is unnecessary for some applications.
