Subscription & Restore Purchases

Hi guys, I'm new at Unity IAP, And I have some questions. I wonder If you could please answer them.
Do you know hot to implement the subscriptions for google play? Because until now, I've never saw a documentation or tutorial about it. If you know something or have a link talking about how to implement it.
Also, I have the question: Does restore purchases exist on Android?. Like, you press a button and the pruchase is back. If yes, Can you please link me to some more info about it?
Thanks.

 

These links may help. You configure subscriptions on your Google developer Dashboard, https://docs.unity3d.com/Manual/UnityIAPGoogleConfiguration.html and https://play.google.com/apps/publish . Purchases are automatically restored upon app reinstall on Android.
