Notification not showing when the message sent to topic

Hi @evollu , When sending the message to topics the Notification isn't showing up, but the data is received.

I have tried sending the message with this:
```js
fetch('https://fcm.googleapis.com/fcm/send', {
method: 'POST',
headers: {
'Content-Type': 'application/json',
'Authorization': 'key=AIzaSyD---'
},
body: JSON.stringify({
"to":"/topics/news",
"data": {
"body": "test body",
"title": "test title",
"color":"#00ACD4",
"priority":"high",
"icon":"ic_launcher",
"sound": "default",
"show_in_foreground": true
}
})
})
```

But when adding the data to the custom_notification the notification show up.
```js
fetch('https://fcm.googleapis.com/fcm/send', {
method: 'POST',
headers: {
'Content-Type': 'application/json',
'Authorization': 'key=AIzaSyD---'
},
body: JSON.stringify({
"to":"/topics/news",
"data": {
"custom_notification": {
"body": "test body",
"title": "test title",
"color":"#00ACD4",
"priority":"high",
"icon":"ic_launcher",
"sound": "default",
"show_in_foreground": true
}
}
})
})
```
