javascript - Google スクリプトでハイパーリンクが機能しない

Question

Google スクリプトにハイパーリンクを挿入しようとしていますが、ハイパーリンクなしでテキストが明確に返されます。以下を確認してください。

if (emailSent != Email_Sent) {
      if (visitType == "Taking") {
        var subject = "Equipment Checked out from Storage";
        MailApp.sendEmail(emailAddress,
                          subject,
                          "Hello" +
                          "\n\nThis is a reminder for myself " + emailAddress + 
                          "\n\nI am " + visitType + " " + amount + " x " + equipment + 
                          "\n\nRemember to return it within 15 days unless i want to keep the equipment" + 
                          "\n\nThanks" +
