Feature request

• Extension name: firestore-stripe-web-sdk

Is your feature request related to a problem? Please describe.

I'd like to be able to modify customer subscriptions through the firestore-stripe-web-sdk package.

Describe the solution you'd like

The firestore-stripe-payments extension allows for the creation of a link to the customer portal of Stripe. This feature is currently not part of the web SDK API, but including it would be a relatively straightforward way to enable the user to interact with their subscription(s).
Better yet, if my other feature request for firestore-stripe-payments is implemented (#606), it'd be amazing to directly cancel/resume/update subscriptions from the web SDK.

Describe alternatives you've considered

The current workaround that I can use is to create a customer portal link directly with the firestore-stripe-payments extension.

Thank you in advance for any assistance provided.
