En esta imagen, quiero que cuando haga clic en el botón tomar una captura de pantalla no muestre el cuadro de diálogo cuadro de línea roja que alguien me ayude

 <button id="cake">Take Screen</button> <canvas id="fake"></canvas> const canIRun = navigator.mediaDevices.getDisplayMedia const takeScreenShot = async () => { const stream = await navigator.mediaDevices.getDisplayMedia({ video: { mediaSource: 'screen' }, }) // get correct video track const track = stream.getVideoTracks()[0] // init Image Capture and not Video stream const imageCapture = new ImageCapture(track) // take first frame only const bitmap = await imageCapture.grabFrame() // destory video track to prevent more recording / mem leak track.stop() const canvas = document.getElementById('fake') // this could be a document.createElement('canvas') if you want // draw weird image type to canvas so we can get a useful image canvas.width = bitmap.width canvas.height = bitmap.height const context = canvas.getContext('2d') context.drawImage(bitmap, 0, 0, bitmap.width, bitmap.height) const image = canvas.toDataURL() // this turns the base 64 string to a [File] object const res = await fetch(image) const buff = await res.arrayBuffer() // clone so we can rename, and put into array for easy proccessing const file = [ new File([buff], `photo_${new Date()}.jpg`, { type: 'image/jpeg', }), ] return file } const button = document.getElementById('cake').onclick = () => canIRun ? takeScreenShot() : {}
