Cross-reference destination

I finnaly achieved what I wanted. I did it in stupidest possible way, but it works. I iterated through all paragraphs and than if that paragraph had style that i was searching for I linked it with corss reference. Here is my code for 3 crossreferences I had to re-link:

var mydoc = app.documents.item(0);

for (var i=0; i<mydoc.textFrames.length; ++i) {
     var frame = mydoc.textFrames.item(i);
     for (var j=0; j<frame.paragraphs.length; ++j) {
          var ap=frame.paragraphs.item(j);
          if (ap.appliedParagraphStyle.name == "Highlight_p") {
               // One
               mydoc.hyperlinks.item("Cross-Reference").destination = mydoc.hyperlinkTextDestinations.add(ap);
          } else if ( ap.appliedParagraphStyle.name == "Highlight" ) {
               // Two
               mydoc.hyperlinks.item("Cross-Reference 1").destination = mydoc.hyperlinkTextDestinations.add(ap);
          } else if (ap.appliedParagraphStyle.name == "Highlight_o") {
               // Three
               mydoc.hyperlinks.item("Cross-Reference 2").destination = mydoc.hyperlinkTextDestinations.add(ap);
          }
          
     }
}

EDIT: I hope someone will find this usefull

I came to conclusion that every crossreference has a hyperlink, and hyperlink has a destination. What I don't understand is how to make hyperlink's destinatio from paragraph style...
