+## Requesting Additional External Tools
+If you have a license for an LTI v1.3-compatible external tool that is not currently available in UTOL, and are considering using it through integration with UTOL, please contact the UTOL Team (`lms-support@itc.u-tokyo.ac.jp`). When contacting the team, please provide information about the tool and its license, as well as the scope of use (e.g., limited to a specific faculty or course, or available for university-wide use).
