Hi! You can do both:

You can confirm a PaymentIntent with an existing Payment Method on the frontend with https://stripe.com/docs/js/payment_intents/confirm_card_payment#stripe_confirm_card_payment-existing for example
You can also confirm a PaymentIntent with an existing Payment Method on the backend. However this might fail if some authentification is required. When that happens, you'll have to ask your customers to go back to your website/app and confirm the PaymentIntent on the frontend this time.

So confirm=true is not required to use an existing pm?

Yes. And if you don't pass confirm: true, then you'll have to confirm the PaymentIntent on the frontend.
