About issuing trial version

Hello.
I think there is a case of the same content somewhere, but I want to ask a question because I could not find it.
Is it necessary for registration even when trial versions of games using Unreal Engine are opened to the public?

Thank you for reading.

What’s absolutely required is reporting of a product which generates revenue. Other than that, I’d say it is best practice to report when there is a release, but not strictly required.
