There are multiple options to access and place assets in InDesign.
- You can continue to use Adobe Bridge to access assets. Bridge is a separate application but easy to use and much more powerful than mini bridge. You can install (and open) Bridge directly from within InDesign.
- Creative Cloud Libraries offers an in-app solution to access, organize, and share assets.
- InDesign also provides the File > Place functionality to browse and place multiple assets in your layout
