In search of a Wireless Keyboard Adapter for my SP7 Type Cover + Compatibility with SP7?

UPDATE: I had to modify the filters on Ebay, but I found one. Turns out there is one seller that has one. BUT the description says it only works with Type 1 and Type 2 covers. Theoretically it should work with the latest cover, the design of the pins has not changed, correct? Also, the offer still stands if anyone on this forum has one to sell. I am looking for a used one if it is cheaper. The Ebay listing costs $44 with shipping included in the price.

Hi all, I am looking for one of these. This is a screenshot of the old listing on the Microsoft Store, back when they used to sell them a few years ago. Can't find one on Ebay or Amazon. Anyone have one they want to sell?

I owned this it never worked after the Gen 2 devices, you could pair it but it wouldn't allowing for the type cover to function.

Thank you for your response! You saved me $40. It's a shame it does not work
