I need to integrate LTI 1.3 flow in one of my tool. I have gone through the documentation in Canvas Configuring LTI Advantage Tools - Canvas LMS REST API Documentation (instructure.com), but I am unable to know exactly how to start the implementation.

Is there any step by step article which I could follow to integrate LTI 1.3?

I have experience with OAuth 2.0 flow implementation in Canvas LMS.
