Best practices for implementing Notifications and Streaming (Gen AI-enabled chats) in Blazor Web App

Question

Need some architectural guidance.

I am building a B2C solution using Blazor Web App model. The entire stack is C# and runs on Azure. I am just trying to understand some best practices for integrating the following capabilities:

1. Push Notifications (pushed through Azure Web PubSub)
2. Streaming of Chat responses (in a Gen AI based ChatBot)

The broad questions relating to the above:

1. Choice of Interactive mode for each of the above scenarios. The Blazor samples for Web PubSub are purely in WASM, but can I just carry that logic to Web Apps? Any other consideration to keep in mind (other than scaling the units on the PubSub service side in Azure).
2. Can I pool Web Socket connection effectively across these scenarios (considering that Interactive Server mode also needs one).

Is EShop the reference I can use for patterns related to my context? Any other references?

Thanks in Advance!
