My first trip with an insulin pump is stressing me out

I'm planning a trip soon and this will be my first time traveling with an insulin pump.

At home I have everything organized, but traveling feels different because I won't have easy access to all my supplies if something goes wrong.

For people who travel with pumps, what do you always carry in your emergency kit? Do you pack extra infusion sets, backup insulin, batteries, extra CGM supplies or anything else people usually forget?

Also, are there any lessons you learned from your first trip that made future travel easier?
