### Describe the bug

I'm trying to use deep link in my android app. Seems like Amplify doesn't support it.

What I send from web Pinpoint:
```
{
"APNSMessage": {
"aps": {
"alert": ""
}
},
"GCMMessage": {
"notification": {
"title": "Merry Christmas",
"body": "Ho ho ho"
},
"Action": "DEEP_LINK",
"url": "link here",
"data": {
"url": "link here",
"screenTitle": "Lorem ipsum dolor sit amet, consectetur adipiscing elit",
"screenDescription": "Lorem ipsum dolor sit amet",
},
"ADMMessage": {
"data": {
"message": ""
}
},
"BaiduMessage": {
"title": "",
"description": ""
}
}
}
```
As you can see, I specified Action DEEP_LINK as it's described here: https://docs.aws.amazon.com/pinpoint/latest/apireference/apps-application-id-messages.html#apps-application-id-messages-prop-apnsmessage-action

Bu on the client side I receive a notification with no deep link.
It means that app gets **android.intent.action.MAIN** as the intent action by tap.
Intent's data is null.

I believe I've done everything correctly according:
https://docs.amplify.aws/gen1/android/build-a-backend/push-notifications/set-up-push-notifications/
https://docs.amplify.aws/gen1/android/build-a-backend/push-notifications/register-device/
https://docs.amplify.aws/gen1/android/build-a-backend/push-notifications/record-notifications/

What could be the problem?

### Reproduction steps (if applicable)

1. Send a FCM push with a deep link
2. Receive it on a device
3. Tap on the notification
Result: App is opened with no deep link. Intent: **android.intent.action.MAIN**, data: **null**

### Additional information and screenshots

_No response_

Start by reproducing the FCM push flow described in the reproduction steps, then inspect the notification tap result, especially the android.intent.action.MAIN action and null intent data. Compare the Pinpoint DEEP_LINK payload with the client-side behavior; done means tapping the notification delivers the intended deep-link data to the app.
