Important thing I forgot to mention is adding "C0" to the list of properties available in lobby. Call "Set props listed in lobby" action with PropNames set to "C0" before creating a room.
For exact property match, you can also use "expected custom properties" feature instead of sql lobby. Set current room property of arbitrary name like "level", add property name to the list of properties available in lobby and create a room. On other client, set the same "level" property to required value and select "MatchMyRoom" option in "random join" action.
