If you’re using the excellent community-built library for Fusion 360 (and unless you’re already familiar with some other CAD software, you probably should be), then the hinge is at the top level of the “Motion” folder.
If you’re using some other CAD package and the hinge isn’t in your parts library, you can download a STEP file for the hinge from the link @BJC posted above and open it in whatever software you’re using.
