In Zephyr Enterprise, I can't search the tests that are created via zephyr app using JQL in Jira

I have installed Zephyr Enterprise, but i can't search the tests that are created via zephyr app using JQL in Jira. 

I can see the issue type Test is available; however, it is not showing any test cases when I select this issue type. I can see these test cases when I go to the app Zephyr Essentials but not able to see them using JQL
