How to open/load Market Place environments?

I download Open world collection and have tried multiple times to figure out how to load this environment and add to a blank project and I cant get it to load. How do I fully load an entire environment bought/downloaded from the market place to a new scene?

Thank you

If I recall correctly that project takes a very long time to open. As for migrating it to another project, here’s the documentation on how to do that. =)

Thank you Jon!
