If your application can reach the Marketplace site, you can browse for apps without leaving your application.
To install an app:
From the top navigation bar in your application, choose > Apps or Manage apps.
Choose Find apps. This is usually located in the sidebar of your application's admin console.
Search by the app name, or choose a category.
Follow the prompts to Install, Buy now, or start a Free trial.
See Finding new Marketplace apps for more information on how to browse for new apps.
Once installation is complete, the app will be listed. You may need to enter a license before you can use the app.
The Exporter Button is placed just on the Tool bar in the Jira Issue Navigator.
