meta key for Jannah theme

Hello

I use the Jannah theme and it has it’s own post views count but allows me use a previously installed counter so I don’t lose counts
BUT I have tried every thing and can’t figure the meta key to use the top 10 views. Can you tell me views meta key
Here is what they say

Post Views Source
If you have a fresh site copy and want to use the default Jannah views, don’t change the default values of these fields.
If you migrating from another theme to Jannah and want to continue counting on the previous views number, get the views meta key from the previous theme and put it instead of tie_views meta key.

If you were using a plugin that handles your views system before installing Jannah and wants to continue using it, choose “Third party post views plugin” from Post views settings, and get the views meta key from your plugin and put it instead of tie_views meta key.

Thank you.
