We are using Jira Software Data Center 8.9.1. I have created a custom report chart, Not Started vs Request Assigned Chart. I want to add it as a gadget to the dashboard. When I went to "Add gadget" on the dashboard, I can't find it. However, I saw "Created vs. Resolved Chart" there to add. How can I add my custom "Not Started vs Request Assigned Chart" as a gadget on my dashboard.
