收听 chrome 底部停止共享按钮的点击事件

Question

有没有办法可以收听使用 angular 共享屏幕时出现在 chrome 底部的停止共享按钮的点击事件

点击停止分享需要调用的方法

 handleStopRecording() {
    this.recordOption.isStart = !this.recordOption.isStart;
    this.showWebcam = false;
    if (
      this.requestType === "screenAndCamera" ||
      this.requestType === "audioAndScreen"
    ) {
      this.handleStopRecordingOption().then(() => {
        this.handleUploadBlob();
        // this.subscribeVideoObserver();
      });
    }
    if (this.requestType === "cameraAndAudio") {
      this.handleStopCameraRecording().then(() => {
        this.handleUploadBlob();
        // this.subscribeVideoObserver();
      });
    }
