Research direction

Review the parent issue elastic/kibana#21354 to understand the context. Look at existing UI tests in the monitoring plugin (e.g., x pack/plugins/monitoring/). The test should check that expiry date in millis is displayed in the license info UI component. Follow the pattern of similar UI tests in the repository, which likely use Jest and a browser testing tool like Puppeteer. Ensure the test is added to the appropriate test file.
