Unable to Chat - Option never appears

[meltedhead]

I can connect to local ollama model for embeddings etc. I can then upload documents and they are indexed successfully but anytime i try to chat then the chat section never appears. If I select a certain document to chat with or search all then i still don't see the option to chat. Any ideas?
Screenshots below showing everything set up

I run the following

# optional (setup env)
conda create -n kotaemon python=3.10
conda activate kotaemon

# clone this repo
git clone https://github.com/Cinnamon/kotaemon
cd kotaemon

pip install -e "libs/kotaemon[all]"
pip install -e "libs/ktem"

Install and unzip PDF_JS_DIST

i have my .env file as below:

Then I start the app. I can test the LLM and Embeddings and everything is working. I can upload files and they are indexed but I can'#t seem to chat? It just never appears?
