Question: How can I notify a client from a function app using SignalR?

[jonBlanco1]

Hi, we have a project that relies heavily on function apps. We also use Azure heavily. How can we notify a client from a function app using SignalR?

For example, our typical flow is the following:

1. Client calls API (regular REST call),
2. API sends message to Service Bus,
3. Function with a service bus trigger starts executing,

So after this function finishes, how can we notify the client using SignalR?
