code: def make_room_alias(chain_id: ChainID, *suffixes: str) -> str:
      
      network_name = ID_TO_NETWORKNAME.get(chain_id, str(chain_id))
      return ROOM_NAME_SEPARATOR.join([ROOM_NAME_PREFIX, network_name, *suffixes])
docs: Given a chain_id and any number of suffixes (global room names, pair of addresses),
      compose and return the canonical room name for raiden network
  
      network name from raiden_contracts.constants.ID_TO_NETWORKNAME is used for name, if available,
      else numeric id
      Params:
          chain_id: numeric blockchain id for that room, as raiden rooms are per-chain specific
          *suffixes: one or more suffixes for the name
      Returns:
          Qualified full room name. e.g.:
              make_room_alias(3, 'discovery') == 'raiden_ropsten_discovery'
