Free browser game for an association of educational municipalities

Hi.

I’ve been working on a survey-like game at my vocational school for students who haven’t picked their professional degree yet to help them figure out what kind of a learner they are.

The game is going to be a free browser game for anyone to access. The game in question is using Unreal Engine 4.23.

However, I’m a bit concerned over the copyrights. Am I allowed to publish the game just like that into the server in our classroom or does the association of educational municipalities need to do some kind of a special license in order to publish it? I am aware that Epic will not take any royalties since this is a free-to-play game.

Thanks.
