[Question]: Subscription ID -OR- token not available (Chrome)

[eightyfive]

How can we help?

I subscribe to User.PushSubscription.addEventListener and I allow the notifications.

• On one Chrome browser: ev.current.token: undefined (while id is available)
• On another Chrome browser: ev.current.id: undefined (while token is available)

Why is that?

More generally when to use id vs token? I can see that to create a Notification via API I need to pass the subscription id to include_subscription_ids... So what's token for?

Thank you in advance 🙏
