Download of a blob url doesn't work on Android

Bug description: I’m generating a blob URL of an audio and putting it into a link tag <a> with the download attr. It works well on the browser, but when I click the link on the React Native Webview nothing happens (no errors).

I thought that it was a permission problem, so I added the WRITE_EXTERNAL_STORAGE to AndroidManifest and requested the permission when the app starts, but it didn’t work.

To Reproduce:

// Create a blob URL and pass it to a link tag
// Try to download the audio on the Webview
const blob = new Blob([], { type: 'audio/webm' })
const url = URL.createObjectURL(blob)

<a href={url} download="audio.mp3">Click to Download</a>

Expected behavior: The audio must be downloaded to the user’s phone.

Environment:

• react-native version: 0.67.4
• react-native-webview version: 11.17.2
