How do I introduce myself during a presentation as a new employee?

I just joined this company not too long ago. In a few days, I will have a presentation with some people I have worked with, some that I have met but not worked with and some people I haven’t met at all. Some people are in my direct team, and some in a different team but same department. This is a monthly meeting, and I also joined last month but I was not a presenter back then and my manager didn’t introduce me last month. I was just a listener. I’m pretty nervous on how to go about this. After this first meeting, I will definitely feel a little more confident. How should I introduce myself briefly? Any tips and advice would be greatly appreciated.
