Trying to find an adapter for the proprietary ssd in my iMac to USB

I recently upgraded the blade SSD in my 2019 iMac to a larger SSD after the platter drive failed (I replaced that one with a larger platter drive as well), and as I was restoring everything from my backup, I discovered that Time Machine had elected to just skip my Documents folder for no apparently reason. The platter was still in a “failing” state rather than outright failed, so I’m thinking if I can connect both drives via an adapter, I can potentially mount the original fusion volume and recover the data. I already have a SATA adapter for the platter drive, but I’m wondering if an adapter exists for the specific proprietary connector on the iMac blade SSD to USB. Or really any way I can read this drive short of sticking it back in my iMac.
