Cannot Find Payment Module in Zoho Creator

Cannot Find Payment Module in Zoho Creator

Hi,

I'm trying to integrate payment processing into a form I have on my application, but cannot find the option to add the relevant field anywhere.  I have configured a Stripe connection (see first image), but there is no option to use it in the Integration field on the form (see second image) or configure a Workflow (see third image).  The only payment-related workflow is a post-payment workflow (see fourth image).

Anyone have any advice?  Thanks in advance.
