Introducing new scooters

Hello I bought a new Fiddle III 50 a short time ago. Unfortunately the dealer did not inform me if I have to drive the scooter and if so, how. I have read many posts, unfortunately these were mostly 10 -15 years old. I read a lot about the fact that you should drive with 1/4, then 1/2 and finally 3/4 gas. In addition, the speed should be as low as possible. What did this indicate with the gas and how do I know that my speed is low? Is it still necessary to drive new models so strictly? I am totally unsure and don’t know exactly what to do. I have already driven about 30 km through the city traffic and have already given over several kilometers of full throttle…. Have I already caused damage? I hope you can help me. Thank you!
