It isn't an "economic confederation". It has a parliament, an executive, a judiciary, and a civil service. I would read the wiki page on the European Union.
The EU parliament can't propose laws, unlike any parliament in the world.
The executive is formed out of national government heads of state, which can veto everything.
Its judiciary and actually all 3 branches are strictly limited in their powers to powers delegated to them (which are weaker than the US Articles of Confederation).
The civil service is covered by the comments above.
In technical terms it is a government, in real life is is strictly limited, albeit growing. No country could operate with the "government" the EU has. France has several million government employees for about 70 million people while the EU has at most 50 000 workers for 450 million citizens).
This is a very complicated topic and I don't really apreciate the condescension inherent in sending me to Wikipedia.
Call it what you want but the fact remains that they can write a lot of laws the member countries must follow, for better or worse. GDPR, Chat Control, etc.
Which government?
