Note: The original callback was incorrectly using the $PAGE output,
which cannot be relied upon in this callback. The best we can do here is
to add a notification to explain the situation.
* BBB has specific completion indicator that need to be taken into account
* Fix mock requests so we can send participant id and then attach events to them
* Refactor slightly the broker to split meeting logic from request (decoding)
* Fix update completion state cron
* Opening braces should be on the same line
* Unwanted MOODLE_INTERNAL
* Behat edit_instance.feature should use "activity editing" page locator
* Coverage indication
* Completion view should work out of the box
* Patch the _user_outline and _user_complete so it works with completion view, while
implementing something better in MDL-74468
* The callback 'xxx_print_recent_activity' needed to be created in order to display
the activities in the block
* Use the print_recent_activity_note api function
