How to recover data from an unmounted HDD of a Fusion Drive on Mac?

The logic board of my 2017 iMac has failed. So I removed the 3TB HDD portion of the Fusion drive and connected it externally to a new iMac for the purpose of data recovery. However, the drive won't mount on the new iMac. If I try to manually mount it in Disk Utility, it shows the error "com.apple.DiskManagement.disenter error -119930868." How can I get my data back from the HDD?
