Is function for checking if guild/user purchased SKU for paid app, exist ?

[taiQui]

I searched in the library if a function to get the list of subscription ( https://discord.com/developers/docs/monetization/implementing-app-subscriptions) from the 'LIST Subscriptions' endpoint but didn't find anything.
My goal is just to check if guild purchased the SKU Subscription to valid use of some specifics command.
Thank you
