[FeatureRequest] --WebPubSub class and UserEventResponse--

I am looking at the documentation for Web PubSub and more precisely [Tutorial: Create a serverless real-time chat app with Azure Functions and Azure Web PubSub service](https://learn.microsoft.com/en-us/azure/azure-web-pubsub/quickstart-serverless?tabs=javascript-v4). There I want to contribute and to add example for Python, but I have 2 concerns. First is that there is no functionality like in Javascript and C# for returning direct response to the caller:

`module.exports = async function (context, data) {

context.bindings.actions = {
actionName: "sendToAll",
data: `[${context.bindingData.request.connectionContext.userId}] ${data}`,
dataType: context.bindingData.dataType,
};
// UserEventResponse directly return to caller
var response = {
data: "[SYSTEM] ack.",
dataType: "text",
};
return response;
};`

I think there is a good idea to add some class which supports the request from webPubSubTrigger and functionality to return the message to the caller.
