Blazor/Maui Hybrid using Entra ID

I'm building an app that needs to run on Web, Android and iOS.

I'm hoping to write it most of it in Blazor using a Blazor Class Library hybrid design with Maui like this: https://github.com/dotnet/blazor-samples/tree/main/9.0/MauiBlazorWeb

I also want to use Entra ID so that users can sign in with Google, Facebook etc. Like this: https://github.com/dotnet/blazor-samples/tree/main/9.0/BlazorWebAppEntra

Can anyone tell me how put these two samples together into a basic example? Thanks.
