DAML Trigger token refresh

Does the DAML Trigger host only read the access token on startup, or does it pick up the new token when I update the token file? If not, it would mean that I have to restart the trigger host if my token expires and I need to provide a new one.

Currently the token is read at startup AFAIK. Implementing a proper Trigger Host with dynamic management and auth is on the roadmap.

Mechanisms for refreshing tokens is a requirement for the under development trigger service.
