Power BI Jira Connection for Sprint and Initiative


I am creating a dashboard to connect to Jira. The Power BI Connector for Jira is not authorized to be used in my organization. I have used a query similar to this to make a connection to Jira: All data not displayed in Power BI from Jira (atlassian.com)

However, I am unable to get the Sprint and Initiative values displayed…is there any information on how I can display those values within my dashboard.

Thank you.
