This is good approach to enable the connection over CORS. For merging, we would need to make those parameters allow_origins=[""], # list of strings allow_credentials=True, # bool allow_methods=[""], # list of strings allow_headers=["*"], # list of strings configurable from the CLI

It's complicated, I'll make them configurable from the CLI in another merge request later.
