FIFA21 for PS4 or PS5?

I managed to get hold of a PS5.
This arrives today.

Do I have to buy FIFA21 specifically for the PS5 or is the PS4 version ok?
I thought FIFA21 includes both versions regardless of which console I buy the game for.

You will almost automatically receive both versions. If you buy the PS4 version, you can upgrade to the PS5 version for free.

You can choose between both. I still use the PS4 version, for example, because you can't use dual shock with the PS5 version and we actually only play locally and with four people.

Thank you.
