Idk, maybe calmly explain why they are asking? Say that they are required to show the license

Say hello my name is officer so and so and according to law such and such I need to see your license

“Good morning sir. My name is officer potato face. I’d like to see your license. I can understand you are uncomfortable showing me that at this moment but according to law such and such I need you to hand over your license and registration now, please”

There was no reason for them to approach the situation the way they did. They didn’t have to act like butt heads. It’s the same as walking up for your morning coffee. There’s no reason to walk up and bark your drink orders at someone without being polite. You don’t have to snap at people and then get irritated when they ask for clarification on your drink orders. Just have some social courtesy when interacting with people
