To integrate Google Wallet and WhatsApp into your system and add them to the deny list, you need to follow a series of steps. First, ensure that you have the necessary permissions and access to the system settings where you can modify the app permissions. The process can vary depending on the device and the version of the operating system you are using. Generally, you would navigate to the app settings, find the security or permissions section, and then look for an option to add apps to the deny list. This might be labeled as 'Block apps' or 'App permissions control'. Once you find this option, you can add Google Wallet and WhatsApp to the list. It's important to note that the exact steps may differ based on your device's manufacturer and the OS version. If you're using a custom ROM or a modified system like Zygisk Next, you might need to consult the specific documentation or community forums for that ROM as the process can be more complex. If you're still having trouble, consider reaching out to the support teams for Google Wallet and WhatsApp for more detailed guidance.
