Good morning, @VasylShtets ...
There may be a variety of ways to introduce yourself to your classmates within your Canvas course. One of those could be as simple as posting a reply to a discussion topic. However, since we here in the Canvas Community do not have access to your course(s), it's pretty hard for us to know exactly what your instructor is expecting of you for this particular task. I highly recommend reaching out to your instructor directly. He/She would be able to tell you exactly where you need to go to complete this task. You can contact your instructor directly in Canvas by using the "Help" menu on the far left-hand side of your global navigation menu, and then select "Ask Your Instructor a Question". You can find more information about this link here:
How do I get help with Canvas as a student?
Hopefully you'll be able to connect with your instructor soon! Good luck!
