• total number of mentors from the partner company who have scheduled at least 1 course

• 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.

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