Check off activities with completion restrictions

Title: A more noticeable visual cue for hidden activities

As a student,
I need to see the complete activities option easily with an obvious visual cue,
So that I don't forget to mark an activity as complete in order to progress.

------------------

Acceptance Criteria:
Please explain what has to be done for the user story to be marked as complete. They’re commonly referred to as scenarios or detailed explanations of what has to be done. You can have multiple scenarios per user story.

Scenario A:
When completing an activity/activities I should be able to easily see the complete activity visual cue.

Priority: SML / LRG

Notes:

Students didn't realise they had to check off activities in order to progress to items that had completion restrictions on them - Source UX Workshops 2020

This refers to when you have an access restriction set i.e. you have to complete one activity before going on to the next activity. In this case, the teacher can choose to make the access restriction info visible so that students then know there is a next activity. However, the setting for making access restriction info hidden or visible is easy to miss! (HF)
