How to check if a PDF Page has no annotations like comments or Fill and Sign

this.syncAnnotScan();
var annots = this.getAnnots({nPage: 0});
if (annots==null || annots.length==0) app.alert("There are NO annotations on this page.");
else app.alert("There are annotations on this page.");

Thank you so much for this JavaScript Code.  I'm looking exactly for this.

But how can I execute or call this JavaSripct Code in my VBA Code? And the second question is I would like

to set my boolean variable blnAnnotaions to false or true regarding from the result of the variable annots from your JavaScript Code.

Sub CheckPDFAnnotations()

Dim App As Acrobat.CAcroApp
Dim PDDoc As Acrobat.CAcroPDDoc
Dim i As Long

Dim blnAnnotations as Boolean

Set App = CreateObject("AcroExch.App")
Set PDDoc = CreateObject("AcroExch.PDDoc")
PDDoc.Open ("C:\Users\Josua\Documents\Test01.pdf")

End Sub
