Question about moving into CSM

Hello everyone happy to be here, I have a question I really hope someone would take out time to answer me thank you as you do so, I have worked as a customer service rep for years now, I really want to transition into CSM but I don’t know how to go about it? I’m wondering if anyone knows the best way to achieve this. Do I need to enroll for online courses to get CSM certification, please can anyone share few ways to help me achieve this goal thank you.
