Give the little hatchling some time to settle in to it's new environment , tank, feeding schedule and to observe you while you are spot cleaning , replacing water, and leaving worms (BSFL or blowfly gents or silkworms) or bugs (crickets , roaches , or locusts ( a few at a time ) in it it's tank.
If it backs off , take the hint and give it the space it needs. It needs to learn you are not going to hurt it and then it'll start learning to trust you and will start being more relaxed with interactions with you.
It'll soon learn you are the food and water provider and you are the one who removes those smelly objects too.
I'd keep handling to a minimum for now, only handle (pick it up) when you have no choice and then only for a few minutes.
I find that if you have some yummy worms or insects , I'd take an opportunity to offer it some food by hand while it's sitting on your lap, tummy or chest and you have the left wrist gently resting on the bottom half of it's tail (this will help discourage it from moving , suddenly leaping off and running off), but be warned , hatchlings have only two speeds , stopped and warp 10 , so be ready to use the right hand as a barrier to obstruct it from leaping or running off (works until they learn they can push under it or simply climb over it).
They soon discover their human's body and hands are a lovely temperature (very close to the preferred operating body temperature for a dragon (36 deg C) and then they start enjoying snuggles.
Spend some time each day chilling next to the hatchlings tank doing quiet calm things and talking calmly and quietly to the hatchling , this will help it learn your voice and learn about you.
Have fun learning about your new spikey 4 legged reptilian child. It's a wonderous adventure and before you know it you'll have a dragon who'll enjoy your company.
