Not able to resolve packages from private nuget

We have deployed a Blazor WASM project into Azure Static Apps and the WASM project references several packages in our private Nuget.

When running the GitHub action as generated by Azure Static Web Apps, we get an error at the Build and Deploy step when restoring the Blazor WASM project as it is unable to find the package(s) that is/are in the private nuget service.

`
/github/workspace/NextWare.Portal.Wasm/NextWare.Portal.Wasm.csproj : error NU1101: Unable to find package NextWare.CoreServices.Meta.SharedModels. No packages exist with this id in source(s): nuget.org`

We have Nuget.Config within the WASM project folder as well as the root folder for the solution.

Here is our workflow as generated by Azure Static Web Apps...
