Unable to Verify if a Pass is Already Added to Google Wallet via Available APIs and SDK

[harshaddmi]

As developers, we aim to create seamless user experiences by integrating with various Google services, such as Google Wallet. However, there appears to be a limitation in the current Google Wallet API offerings: there is no official API or method to check if a pass (e.g., a loyalty card, ticket, or other digital passes) has already been added to Google Wallet.

Steps to Reproduce:

• User opens the application for the first time and sees the "Add to Google Wallet" button.
• User adds the pass successfully to Google Wallet.
• User reopens the application and expects to see a "View in Wallet" button if the pass has already been added.

Expected Behavior:

• An API or method should exist to check if a pass has already been added to Google Wallet, allowing developers to toggle between "Add to Wallet" and "View in Wallet" buttons accordingly.

Actual Behavior:

• There is no available method, SDK, or API in the current documentation to verify if a pass has already been added to Google Wallet.

Reference:

• Google Wallet API for Loyalty Cards only provides an "Add to Wallet" callback but lacks a mechanism to check the status of a pass.

Request:
If there is an existing API or documentation that covers this functionality, please provide a reference or guidance.
