Grant Entitlement for user with active subscription

Hello,

We have a use-case:

1. User is active subscriber on a monthly plan
2. They trigger `redeem` functionality
3. They get 1 month free from their subscription (meaning next month they are not getting billed, however month after that - they are getting billed again)

We know that via RevenueCat it’s possible to make if user is not a subscriber. However, would that work for subscriber’s case?

If it’s not possible - what would be recommended scenario for implementing this case? We would like to explore possibilities to give not only 1 month free, but also other various durations.

We were also thinking of this scenario:

1. User is active subscriber on a monthly plan​​​​​​​
2. They trigger `redeem` functionality
3. User sees `offer` page with `1 month free + regular monthly` billing
4. They claim the offer
5. User’s previous subscription period ends, their new subscription starts with 1month free

Would that work? Ideally - `entitlements` would make it much easier as we would not need to create any extra offers.

Best
