Edited a PDF, old highlights/annotations won’t appear in new file

I made some minor edits on a PDF using an external app. Just some minor spelling corrections. But I can’t get my annotations from the previous version of the file to connect to the new PDF book. I was able to merge the mindmap so that when I go from document mode to mindmap I am taken to the right map. But the highlights and notes do not appear in the document itself.
Help please? I’ve done this before a couple of time, but I can’t seem to find the answer this time around. (promise to bookmark it this time)

Found it! It’s under “Manage” when previewing the text in Mindmap.
