Great question! I’ve experienced the same, so I totally understand. The thing is, they hired you for a reason. You’re the technical trainer, they’re not. This is your realm. If they were better than you, then they should be the ones conducting the training, not you. So same mindset, you’ll be doing their people (because they’re from management) a disservice by thinking about yourself, being nervous, and delivering in a rush. It’s not about you. It’s about your main audience.

I also suggest that you immerse yourself as much as possible to environments where you present to people in management and senior leadership. The more exposure you get, the more you get used to it. You’ll realize, they’re just normal people too, just like you. It’s just that they had the courage to step up and become a leader. I’m suggesting you do the same. Step up, and be in environments where you can engage with leaders more often. Build that confidence. Soon enough, you’ll become a leader yourself.

As they say, you are the average of the 5 people you spend the most amount of time with. Make it count. Spend time with leaders.

Hope this helps!
