It’s been a few years since I’ve used LockDown Browser or learned about any new features, but I recall that it used to be that the LockDown browser link was provided by the instructor. The links are unique to each school, so providing you with a link here might not be possible. I suggest that you reach out to your instructor via Canvas to see if he/she can provide you that link. You can contact your instructor by following the instructions in this Guide: How do I get help with Canvas as a student?. If you are still not able to get a link from your instructor, then try reaching out to your school’s Online Learning / eLearning / Distance Education team. They may be able to point you in the right direction. Good luck!
