Free for the month items (Other engine usage?)

What I’m wanting to know are the free for the month items(non epic), are they free to use in other engines, as this is the default 3rd party license?

I know anything I buy (with a default license) can be used in both engines.

I’d not expect the free for the month items to be available for use in other engines but I didn’t see a different license on download.

Maybe I missed something, hence the question.

Kind regards,

Yup, anything that’s not created by Epic is free game.
