The feedback URL uses template=insiders-feedback.md, but this repository only has .github/ISSUE_TEMPLATE/bug_report.md and feature_request.md. As-is, the template query param won’t select a valid template; either add the referenced issue template file or update the link to an existing template (or use ?template=feature_request.md / bug_report.md).

The URL is rendered as plain text (and lacks an https:// scheme), so it may not be clickable and isn’t keyboard-accessible. Consider using Primer’s Link component with a full URL (and if using target="_blank", include rel="noopener noreferrer") so users can reliably open the feedback page.

It isn't clickable as this isn't supported in MCP Apps
