How to check if a pass has been added to Google Wallet?

import com.google.android.gms.pay.PayClient

private val walletClient: PayClient = Pay.getClient(this)
walletClient.savePassesJwt(passJwtToken, this, addToGoogleWalletRequestCode)

But I can't find a way how to check if the pass has already been added to Google Wallet to show the correct text on the button. Because, in the guidelines, there are two types of buttons :

    The devsite here outlines how to link to an existing pass for your users, but this doesn't tell you if said pass is already existing. The best way to track whether a pass is saved or not is to set up a table which references your callbacks to know if the pass with a given ID is currently saved.
