Selecting an unanchored frame

Beackground

I have a few old documents (~150) that are having issues. When opening these documents one graphic file cannot be found. I know this file was not checked into our source control system, therefore it's missing.

I can see the name of the missing file, for the moment I skip the dialog and continue.

I don't have the file (since it was not checked in) so I want to delete it from the document and insert a new one.

If I run a LOR/Imported Graphics I see file is located on page 42. If I navigate to that page I don't see the expected gray box to indicate the missing file.

I run the script below and I get that the file is located in an unanchored frame, that I cannot see.

Question:

Is there a way to select either the graphic or the unanchored frame in order to delete it? Thanks for any ideas...

var oDoc, oGraphic, oFrame;
oDoc = app.ActiveDoc;
oGraphic = oDoc.FirstGraphicInDoc;
if(oGraphic.ObjectValid()){
    //good to go
     while (oGraphic.ObjectValid()) {
         //
         if (oGraphic.type == Constants.FO_Inset){
             oFrame = oGraphic.FrameParent;
             alert(oGraphic.InsetFile + "\n" + oFrame.constructor.name);
         }
         oGraphic = oGraphic.NextGraphicInDoc;     
     }
}
