How to config causal-service for self-hosted Rath

[AlexLin625]

After reading Issue #365 , I tried

1. Mannualy deploy the service as docker service and expose its port.
2. Add the service into the Rath docker-compose config file

  causal-service:
    restart: always
    network_mode: service:base
    build:
      context: ./services/causal-service
      dockerfile: Dockerfile

And Rath app behaves same.

... there is no option to select an "Algorithm," only blank choices are available.
