I am adding ApplePay using Chase. Chase provided me with the certificate signing request and we created the certificate, but they say they cant provide us with the private key used to create the .csr, so every time I try to create the ApplePay Payment Session (https://developer.apple.com/documentation/apple_pay_on_the_web/apple_pay_js_api/requesting_an_apple_pay_payment_session), I got an error as I am passing only the certificate. If I create the .csr then I can sucessfully create the ApplePay Payment Session because I also have the private key, but as it wasnt created by Chase, it doesnt contain their info and they reject it. So, It is possible to request the ApplePay Payment Session without the private key? I tried creating an p12 file, but I dont get that option as it doesnt find the private key in the pc and I tried to install the certificate in the store, but when I read it, it doesnt have the private key and it fails in Apple
