How to publicly share an app?

Hi,

How can I publicly share a Zoho Creator app?
When I want to share I only have these options:

I have looked how to share publicly on your website and I have found this:
https://www.zoho.com/creator/help/application/application-sharing.html
On this webpage, there is a 3rd option "Make public to all visitors over the web".
Why is this 3rd option not available for me?

Regards, Chris
