Hi team,

I am a part of research engineering team, and I have a redemption code for a course. I wanted to use the code on NVIDIA cosmos course, Introduction to NVIDIA cosmos for physical AI and for some reason link go redirected to a different workshop and I used the code for that. Can you please cancel my code for it so that I can finish the introduction to NVIDIA Cosmos course ?

**Find the Bottleneck: Optimize AI Pipelines With Nsight Systems. I got enrolled to this workshop. Can you please cancel so that I can use it on the course I want to finish,**
