How to list all blob image files in ionic-running localhost?

Hi there,
I’m working on my first project of Ionic-Angular
After I call:

const capturedPhoto = await Camera.getPhoto({
      resultType: CameraResultType.Uri,
      source: CameraSource.Camera,
      quality: 100
 });

I see that a new blob image is created with URL like: “blob:http://localhost:8100/82300d7b-c5b8-4bca-8779-c6b140046e73
I want to know how many blob images have I created. How can I list all of those images ?
Thank you!
