Add Key button not showing on REST API setting page


I’m using the latest version of Gravity form 2.4.15
I need to set source_url (so that the embed_url points to the current page and not current form URL). From what I understand, it is only available via the /entries endpoint, and not possible using /submissions endpoint.

The developer guideline says, I need to obtain consumer key via the setting page.
The REST API setting page only shows this Authentication ( API version 1 ) fields which contains Public and Private keys.

How do I obtain the consumer key for API v2?

I recommend opening a support ticket for this issue, but I will leave this open in case someone has some insight.
