PDF - Vertical Scroll, Annotations and Adding/Accessing Bookmarks

I want to attach PDFs to my notes (which have images on them and so cannot be OCRd), if a plugin could let me vertical scroll through the PDF (since some PDFs run into 50,100,200 pages) or directly go to page numbers that would be good. It would also be helpful if I could make markings with the Apple Pencil on the side OR just be able to add/access bookmarks to jump to relevant portions.
This is on the iPad, I’ve tried to find solutions on existing plugins, but none worked for me unfortunately…

I now see that the desktop app does exactly what I’m looking for…now if only the mobile version could do the same it would be perfect
