Copilot doesn't have a concept of "context". But the server does keep track of conversations.
The bot will store conversation metadata in the Matrix room attached to its initial response to a query. This metadata is encrypted and contains the necessary information needed to load the conversation and continue talking to the user.
You need to generate your encryption key first:
python3 new-fernet-key.py
This will print a string. Copy this to your config.yaml
in the event_encryption_key
field in the copilot
section.
