Achievements needed in demo if full version includes it?

Hi there,
I want to release a demo version of a game that´s also available as a full version. As the full version has achievements on other platforms (Playstation and Xbox) I read that they are also required in the epic store version of the game. Now is my question if I have to include the achievements in the demo as well or should they just be unlockable in the full version (like on playstation for example)?
And if they are not required: Do I have to login the player at all in the demo if I just need it for the achievements?
Thank you,
Benjamin

I think this policy is not the smartest move of demanding feature equality.

We have for example several older games we won’t release on Epic Game store simple because the engine used is in one case UE4.11. We won’t upgrade the engine to 4.27 or even 5 and rerunn all QA just to release it on Epic Game Store. Because of this we will pass and due to those policies “we want everything others have” we might pass to release on EGS at all.
