How do I play Rocket League with a 2nd account?

On the PC. I come from the Playstation and you could just create a new profile and then have 2 Rocket League accounts. How does it work on the PC? Do I have to download it again from Steam and create a new account? (Downloaded it from Epicgames). Or is it enough if I log out somewhere?

I think you have to create another account in the Epic Games Launcher and then start Rocket League from this account.

You can no longer buy it on new accounts via Steam unless you want to pay 100 euro for a key.

I think if you downloaded it via epic just log out of Epic and log in to a new account, then start Rocket League.
