Commercial using "free for the month" assets (UE4-27, UE5-0)

Hi Epic Games, MarketPlace and developers.
I am creating a commercial project for sale (video, rendering, learning, online school).

Can I use “free for the month” assets in this project?
The buyer cannot independently download and prepare free for the month assets.
This is what I’m doing now for the buyer.
The source of project will be sold.

So, can I use “free for the month” assets (January assets, February assets, etc.)?
Thx.
