If Michael is in Israel, I don't think he's working with 120 or 240V circuits.
More like 100V but, the concepts are the same.
Unfortunately, I don't have a clue as to what he's referring to without correct terminology.
If you only have two wires then you can 't do it. You have hot in and switched hot back to the fixture. You don't have the return wire to use for a receptacle. Doesn't matter if it is 120 or 240. You need three wires to make a switch receptacle combo work.
Looking at the pictures it appears that (on the back image) power in goes to the terminal with the brown wire(right). Return power goes to the left connection(this is the wire you are missing). Ground goes to the upper connection. Fixture switched power goes to the red wire.
