Some URLs point to nothing

[Telokis]

For the front service, the following environment variables are defined (Here):

      - CALENDAR_URL=http://${SERVER_ADDRESS}:8095
      - GMAIL_URL=http://${SERVER_ADDRESS}:8088
      - TELEGRAM_URL=http://${SERVER_ADDRESS}:8086

However, there are no services associated with these ports, making the deployment either wrong or incomplete.
This is not mentioned in the README.
