Digital Commons/BookReader Full functionality?

Hello,
My goal is to find out if I can use BookReader to view our content - without hosting our content on archive.org

Our content is hosted by Digital Commons (bepress). Digital Commons does support BookReader's third party API: On an item's submission form, there's an "Internet Archive BookReader" field where I can add the item's URL:

However, when the item is viewed in BookReader, search and full screen functionality is missing: (https://dsc.duq.edu/jfk-documents/13/)

Is that because we're using BookReader as a third party API?
If so, there any way to get a fully functional BookReader WITHOUT hosting our content directly on Archive.org?

Please note: I have read through the documentation on [Github](https://github.com/internetarchive/bookreader/issues) and can't find anything about Digital Commons/BookReader. Thank you for your help! -Licia
