How to get on-premise version of Appian
1. Want to test an on-premise version of Appian.
From Appian forum, I found something like the picture below.
But it doesn't provide any installers.

2. Found a link for "Requesting and installing a license."
https://docs.appian.com/suite/help/21.1/Requesting_and_Installing_a_license.html

but when I click the "Licenses" link within the link, the picture below comes up.

Could I get specific steps that I can follow to get an on-premise test version of Appian?
