In testing this, it appears the function only works with truecolor or grayscale images, not binary, so that is why I multiplied by 255. Otherwise, the code comes straight from the example I linked to. Since your image is the QR Code, it was not necessary to specify an roi.
Note: this solution requires the Computer Vision toolbox.
I = imread("https://www.mathworks.com/matlabcentral/answers/uploaded_files/1232262/image.png");
I = I*255;
imshow(I)
[msg,~,loc] = readBarcode(I,"QR-CODE")
msg = "QR Code Generator by TEC-IT"
loc = 4×2
77.5000 471.5000 77.5000 77.5000 471.5000 77.5000 406.0000 406.0000
xyText = loc(2,:);
Imsg = insertText(I,xyText,msg,"BoxOpacity",1,"FontSize",25);
Imsg = insertShape(Imsg, "FilledCircle", [loc, ...
repmat(10, length(loc), 1)],"Color","red","Opacity",1);
figure
imshow(Imsg)

You need the Computer Vision Toolbox R2020a or later
