This is highly dependent on your bank. For example, Bank of America lets you view and delete any cards that have been added to a digital wallet right on their website.
Theoretically, it would allow a pretty neat feature of being able to manage all merchants that have a copy of the card in the banking app and revoke said copies – but since token use is not mandatory, that would be fairly confusing, so I haven't seen this yet as far as I remember.
FWIW, India has taken a pretty radical step towards that future at a regulatory level by effectively mandating merchants to no longer store the underlying card number and use tokens instead. I suspect that such an interface would be more common there, but I don't have any personal experience.
Only digital wallets. Specifically, Apple Pay, Garmin Pay, and Google Pay.
Heaven forbid if I try to add a card to an Apple Wallet on a Mac where no iOS or Android app exists.
