Clicking on Cancel - will still integrate Authorize.Net, but it will not make it the Default Gateway. Clicking on Confirm - will integrate Authorize.net and make it the Default Payment Gateway.
NOTE: Kindly be informed that disconnecting Stripe is not necessary to connect to Authorize.net. You can link both gateways through the integrations page.

PayPal will still be operational alongside Authorize.net/Stripe in order forms, whichever gateway is designated as the default.
