Hai! There are a number of ways to do so. I assume that you need to record either for your own video use or future reports, and I believe OBS and GeForce Experience are both great tools for us players to record our gameplay!
You can download these free apps with a simple search, and there are plenty of YouTube videos online that will teach you how to use them!
For now, I will lock this thread. However, should you have any questions, feel free to start a conversation with me about this. c:
