How can I renew Audible membership from the App Store?

I used to have an audible membership but I cancelled it a while ago.

I want to renew it again, but cannot find a way to do it on the app or browser.

I contacted audible support but since i purchased it in app (through apple) They cant do much for me.

This is so annoying! How can i renew my membership?

It is not in my subscriptions, and i dont want to create a new account as I have quite a few titles in my library.

Any help would be appreciated
