Does Google send a notification when a trial period ends and they automatically initiates billing against the credit card of the user?

Related to this, I only see:
When the trial period ends, Google Play automatically initiates billing against the credit card that the user provided during the initial purchase, at the amount set for the full subscription, and continuing at the subscription interval.
I am currently handling different types of notifications (depending on the notificationType field) but I don't know if it's possible to track trial periods.
I didn't receive any answer from Google support.
However, after deployed a webhook and receive notifications from Google, I confirmed they send an event with notificationType = SUBSCRIPTION_RENEWED when the trial period ends and the user's card is charged.
