How can I add Link-OBJR (object reference to link annotation) using pdfbox.

       `PDAnnotationLink txtLink = new PDAnnotationLink();
        PDRectangle position = new PDRectangle();
        position.setLowerLeftX(PDFUtils.lw_lft_x);
        position.setLowerLeftY(PDFUtils.lw_lft_y);
        position.setUpperRightX(PDFUtils.tp_rgt_x);
        position.setUpperRightY(PDFUtils.tp_rgt_y);
        txtLink.setRectangle(position);
        txtLink.setHidden(true); 
        txtLink.getCOSObject().setInt(COSName.STRUCT_PARENT,1); 
        PDActionURI action = new PDActionURI();
        action.setURI(PDFUtils.link);
        txtLink.setAction(action);
        page.getAnnotations().add(txtLink);
        PDObjectReference pd= new PDObjectReference();
        pd.setReferencedObject(txtLink);
        structureElement.appendKid(pd);
        currentSection.appendKid(structureElement);
        structureElement formBuilder.addContentToParent(COSName.P, null, page, structureElement, PDFUtils.mcid);`
