+To enable the FeedbackXBlock report in the instructor dashboard, you can use the following tutor inline plugins:
+
+.. code-block:: yaml
+
+    name: feedback-xblock-settings
+    version: 0.1.0
+    patches:
+      openedx-common-settings: |
+        FEATURES["ENABLE_FEEDBACK_INSTRUCTOR_VIEW"] = True
+        OPEN_EDX_FILTERS_CONFIG = {
+          "org.openedx.learning.instructor.dashboard.render.started.v1": {
+            "fail_silently": False,
+            "pipeline": [
+              "feedback.extensions.filters.AddFeedbackTab",
+            ]
+          },
+        }
+
+To enable this plugin you need to create a file called *feedback-xblock-settings.yml* in your tutor plugins directory of your tutor instance
+with the content of the previous code block, and run the following commands.
+
+.. code-block:: bash
+
+    tutor plugins enable feedback-xblock-settings
+    tutor config save
+
+
+You can find more information about tutor plugins in the Tutor `plugins`_ documentation.
