How do I setup Apple Cash in a Mac Wallet under the Mac OS Preferences

I can setup a Wallet on an iPhone under the iOS with an Apple Card, Credit and Debit cards and an Apple Cash card. I can add an Apple Card, Credit and Debit cards under the Mac OS Preferences but I cannot figure out how to add my Apple Cash card on my Mac. I tried to add it manually and the Wallet took the photo of my Apple Cash card on my iPhone but then would not add it. When will Apple support my Apple Cash card on my Mac ???
