How can I enable test mode of Stripe in KEAP to test purchase?

I understand there are two ways to enable Stripe test mode (and maybe any payment test mode).

  1. The app where the payment gateway (stripe) is integrated has a test/live toggle option.
  2. The app where the payment gateway (stripe) is integrated has the option to add test API and secret key that is been provided by the payment gateway.

My questions are:

  1. Has KEAP integrated with Stripe at such level that I can toggle between live and test mode for purchase ?

  2. Is there an option anywhere under the Stripe integration inside KEAP that I can put the test API and secret key provided by Stripe, in the KEAP so I can test purchase?
