Zoho Inventory as connector in Zoho Creator

Zoho Inventory as connector in Zoho Creator

Hello,

It doesn't appear that Zoho Inventory is one of the many built in connectors in Zoho Creator? I see that there are non-Zoho inventory applications that have built in connectors such as Cin7, which leads me to believe that I'm missing something (i.e. why would a 3rd party service have a built in connection and not a Zoho native app)?
