If the logged in user is a from a partner NGO, the following data will be shown:

• total number of students from the partner NGO who have enrolled in at least one course and who haven't cancelled it
• total number of courses in which the students from the partner NGO have enrolled (completed + not completed)
• total number of hours until the current date, corresponding to the lessons that haven't been cancelled in the courses (1h per lesson)

The data will be retrieved from the /api/v1/partners/{partner_id}/dashboard/stats endpoint.

If the view mode is set to All MWB participants, the endpoint will be /api/v1/partners/dashboard/stats.

The results will take into consideration the selected year and the view mode (data for own organization / all MWB participants).
