Where are GameDev store history/receipts?

Hi guys!

I'm a really old user here, but I don't talk too much - in the past, I used this space to follow up gamedev news and purchase some assets in GameDev store. But, GameDev store doesn't exist anymore and I need my purchase receipts now (I intend to use some sound tracks in a project and I wanna avoid possible future legal problems.

How can I proceed to get it? I looked around whole website and I didn't find anything suggesting how to get receipts from old GameDev purchases.

Thanks in advance!
