Getting from store entry to required achievement to buy item

[Woeler]

Hello everyone,

I'm looking to get to the id of the achievement required in order to buy a certain item from a store. Specifically from Furniture vendors that sell special furniture once you have completed an achievement.

However, I cannot figure out how to get from the store entry to the tied achievement id. Does anyone have any guidance on this problem? I'm starting to doubt it is even possible.

Thank you!
