Check if user has already bought something

I am currently building an app in Flutter using RevenueCat for the in-app-purchases.

I now want to know for each user, if he has already made an in-app-purchase, since I have trial subscriptions activated. I need this information, because I want to adjust the UI in case a user registers with a new account that I haven't seen in RevenueCat so far. In this case, he won't be able to use the trial subscription again, since Google/Apple prevent this.

I am using a custom ID for every user in my app and I use this ID for RevenueCat aswell, one could just create a new account and get a different user id. Ass far as I understand, in this case, this looks like a "new" user to RevenueCat which has no subscriptions. I think the solution would have to check the GooglePlay-Account for an already purchased subscription

So far I have not found a way to find out, if a user has already made an in-app-purchase. Any ideas on how to achieve this?
