Unlink AIY Voice kits from google home

[ADM.Destroyer]

I have a lot of AIY failed attempts still linked to my google account. I can't unlink them.
When I click unlink it takes me to the linked devices page, and they don't show up there (see the video: https://streamable.com/98bc90)

Unfortunately, I can't turn it on, as the SD card has been wiped(I even gave away the whole kit).

Any ideas on how to get rid of them ?

I saw somebody addressed the same issue on Reddit, but nobody came up with a solution. I think you can raise your issue here.
