1. Pull latest changes from this repo and open the sample's folder.
2. Comment out this code in teamsapp.local.yml: This is to make sure you are using the latest code changes, not what is latest published code.
3. Add AOAI key and endpoint or OAI key to .env, .env.local.user, and update azure.bicep and azure.parameters.json with the key and/or endpoint.

.env.local.user:

.env:

azure.bicep:

4. Run the sample and if no problems detected, please add a checkmark with your name above. If you do come across any problems, please list details of which sample / what model(s) you used, take screencaps of the chat log, and other error messages or related context, and post them as a comment here. Feel free to put an ❌ with your name in the tasklist above.

Having more than one person per sample per LLM would be much appreciated. Thank you!
