I cannot add my debit card to apple wallet

I wanted to add my debit card to the Apple wallet. The apple wallet app says that I need to find the ‘add to wallet’ button my banking app to add it. I tried and couldn’t find it in the app. Please, make this feature available. I don’t want to carry a card all the time. Android users have gpay that supports such feature where I can add my card manually and use my phone as a contactless transaction enabled card. But not on iOS. Please, at the minimum reply with a affirmation that it’ll not happen.

Apple Pay is not available in India. So even if Jupiter wanted to enable this, they couldn’t.
