How to populate a TextField with an App State (or Action Output)

Troubleshooting

I am failing to load an App State variable into a TextField. (For context, this is extracted text from a Pdf. The text should load into a chat TextField so it can be submitted within a prompt to OpenAI).

So frustrating as the difficult part is complete. But I can't get the extracted text to load into the TextField widget. The information is there, it just needs to go into the box!
