Can we import assets from City Sample and use them in a univesity research-based project?

Hey guys, we are trying to build a platform based on Unreal Engine 5. On that platform, people can do scene generation, object interaction, etc. User can also generate data from that platform to do further research, like computer vision, artificial interlligence.

At current stage, the platform is still under construction. I am using existing free assets from Epic Marketplace.We may purchase some assets to make our platform look like real world as well.

I am not sure if we need authority because in future, we hope to open-source this platform so that more people could use this platform and extend this platform. For example, I import some vehicles from City Sample and character can interact with the vehicles. I also use animation from mixamo.com to be the interaction animation.

Any suggestion would be appreciated. Thanks in advance.
