I don't know how Local Push Connectivity works

I was seeing the example that is provided by Apple and I don't really know how to implement the network extension. I searched in the capabilities and I tried to add a Network Extension target but I didn't find the provider type for App Push Provider. I am new in apple development and it is probably that it is a easy way to do this but I didn't find how. PD: I am using Xcode 13.3.1
