How to define intent URL within client::notification?

Hello!

I'm trying to define URL to open another app after I click on the notification.
So, it seems, URL like that should do the trick:
```
{
"extras": {
"client::notification": {
"click": {"url": "intent://www.youtube.com#Intent;scheme=https;package=com.google.android.youtube;end"}
}
}
}
```
But nothing happens.
Any suggestions would be greatly appreciated.
