To access the admin interface of VisualScript in Jira, click on "Settings" then "Apps". In Confluence, click on "Settings". You should see VisualScript with the option to "Create/Edit Reports".
You can import a set of reports by clicking on the "Import Reports" button in the lower left corner of the VisualScript interface.
VisualScript will expect a "vse" file.
The import process will check for any conflicts like reports with the same name.
