react-native-dialogflow | Native Bridge for the Google Dialogflow | Artificial Intelligence library

I am building a chatbot app using react native and dialogflow. I have the general chatbot working (code below). My next step is that I want to store the user's name (using react native) on their device (this I know how to do) and also send this name to dialogflow so that the bot can respond with the user's name (No idea how to do this last step). I have done a lot of research on how to accomplish this, and perhaps I am just too new to dialogflow, but I have failed to figure out how to do this. From what I have gathered, I believe I will need to set an entity from my react.js files, which then can be accessed as a parameter in dialogflow. I see that the react native module dialogflow has a setEntity method, but with dialogflow_V2, this has been moved from /setEntity to sessions.setEntityType. I am totally confused on how I would implement this in dialogflow_V2 (and how "/" differs from "sessions."). I noticed that when I send a query request, there is a java object returned that has a session key. Do I need to somehow use this session key to use setEntityType, and if so, would this not only be applied on particular queries? Any clarification or guidance would be very much appreciated. Thank you.

The main screen for my chatbot is provided as code below (note it uses the new functional component style, not yet as commonly seen as using classes). To run this, one would have to connect this screen to the app.js file using react-navigation, and create a env.js file (sensitive information), that can be accessed from dialogflow. A nice tutorial for how to do this using classes is in this link: https://blog.jscrambler.com/build-a-chatbot-with-dialogflow-and-react-native/
