       const formatLogResult = await formatters.formatLog(thread, threadMessages);
-      // formatLogResult.content contains the log text
-      // Some code here that uploads the full text to Pastebin, and stores the Pastebin link in the database
+      const pastebinUrl = await saveToPastebin(formatLogResult); // saveToPastebin is an example function that returns the pastebin URL for the saved log
+      return { url: pastebinUrl };
     },

-      // Find the previously-saved Pastebin link from the database based on the thread id, and return it
