Hi @Raleigh27123095jx05,
You can ask the current owner to invite you to edit the project, and once you accept the invitation, you can duplicate the project. This will make you the owner of the duplicate one, which can now be your primary project.

The project you get invited to will come under the 'Shared with you' tab & the duplicated project will come under 'Yours'
Best,
Amitej
