I need to move all objects of a very large document that is intended for print away from the spine

* Current version of Adobe Indesign used on an M1 Mac Mini

I've produced a fairly large file that is intended for print publication as a book. I used the templates the printer provided, but all the text is much too close to the spine of the book. I need an easier way of moving every object on every page away from the spine binding. There IS enough margin on the outside to accomodate this without the text falling into the bleed area. I found a script that is supposed to do this, but the script doesn't work with the current version of Indesign. Some tips or help please? I really don't want to have to manually do this page by page if I have another option. Adjusting the Master Pages will not help either as the document pages do not all adhere to the Master Page settings. Thank you!
