After you've installed the plugin, you'll need to link domains to organizations.
The plugin can only be configured by JIRA Administrators that have JIRA Service Desk Application Access.
Then, on the left side, go to 'ORGANIZATIONS AUTOMATION' and click 'Rules Configuration.'
Click '+Add Rule' to create a new rule and fill in the Project, Organization, and Domain areas.
After you've added all of the rules, click 'Save'.
