What alternative methods exist to save files locally exclusively in Cocos Creator 3.8.7 editor environment?

let dataURL = canvas.toDataURL('image/png');
                 let img = document.createElement("a");
                 img.href = dataURL;
                 img.target = "_self";
                 img.download = "screenshot.png"
                 img.click()
