How to determine if a user is eligible for an introductory offer or promotional offer?

How to determine if a user is eligible for an introductory offer or promotional offer or neither when they just view the subscription page in APP without submitting a subscription? We are using apple server notifications V2. My goal is to display different offer pages to different users on the subscription page according to their eligibility. But currently, we can only recognize the user's eligibility after they have submitted a subscription order.

Hello!

Introductory offers are only for new users that have never been subscribed to any of the subscriptions in a given subscription group, whereas promotional offers are for existing or previous subscribers.
