How to display Zephyer Scale for JIRA Version

Assuming you're on the Cloud version, I can find version history in the Jira Marketplace: Zephyr Scale - Test Management for Jira - Version history | Atlassian Marketplace

If you're on the Data/Server version you can find the version history here: Zephyr Scale Server/Data Center Release Notes | Zephyr Scale Server/Data Center Documentation (smartbear.com)
