Where to find vapid_email?

Configuration
1

I’m setting up html5 push notifications and it’s asking for the vapid_email, which is the e-mail account associated with your Firebase project.
I can’t find how to get it, though. Where is it?

Nevermind, it’s under Settings > Service accounts > Firebase Admin SDK > Firebase service account.
Or short link that asks you to choose a product:
