How download audio file and play with native-audio plugin?

I’d like to play mp3 audio in my ionic capacitor app.
I download file from server and then I want play it.

I used:

@capacitor/filesystem in order to download file
@capacitor-community/native-audio in order to play audio
Download file:

```typescript
let option = {
path: "sample.mp3",
url: "https://file-examples.com/storage/fe9f92926365baacd9d565f/2017/11/file_example_MP3_700KB.mp3",
directory: Directory.Data,
recursive: true
} as DownloadFileOptions;

try {
const result = await Filesystem.downloadFile(option);
console.log('Wrote file', result);
this.downloadUri = result.path!; //save path into global var
alert("OK " + this.downloadUri);
} catch(e) {
console.error('Unable to write file', e);
alert("ERROR");
}
```

Play audio

```typescript
await NativeAudio.preload({
assetId: "sample",
assetPath: this.downloadUri, //use saved path
audioChannelNum: 1,
isUrl: true
});

await NativeAudio.play({
assetId: 'sample'
});
```

Download is OK but when I play I receve error:

```log
Wrote file {path: '/DATA/ciao.mp3', blob: Blob}
Not allowed to load local resource: file:///DATA/ciao.mp3
```

I’m testing on web browser (ionic serve mode). If I use local audio file (stored into assets/sound folder), it works

could you lease help me?
