Artboard name to Content

I work with the script and it works very well. But I can only use one Active Artboard at a time. Can someone help me so that all artboard names are automatically written into the content

1000 Thanks

#target illustrator
function test(){
    if (app.documents.length == 0) {
        return;
    }
    var doc = app.activeDocument;
    var newText = doc.activeLayer.textFrames.add();
    var idx = doc.artboards.getActiveArtboardIndex();
    var currentArtboard = doc.artboards[idx];
    newText.contents = currentArtboard.name;
    newText.top = currentArtboard.artboardRect[1] + 10;
    newText.left = currentArtboard.artboardRect[0] + 10;
    newText.textRange.characterAttributes.size = 20;
};
test();
