How can I identify users completely read / viewed all lessons for a particular course in Moodle

How can I identify users who completely read / viewed all lessons for a particular course in Moodle? I created one course and enrolled 3 users in it, created course have 10 topics, each topic contains some information. I configured mobile app and connect to it. I got the course information correctly, but I didn't get any information about users completely viewed all lessons/not. Moodle provides any options for tracking lesson.
