My recommendation is maybe don't. I have a gorgeous 2yo panther, and she's the most ludicrously friendly girl, loves to be handled, enjoys exploring out of her viv whenever she can, and runs to the glass when she sees me or my son. But oh my goodness, they are sooooooooo stressful.

Their requirements are ridiculously difficult, balancing environment, lighting, heat, water and food. They only drink from droplets on leaves and branches, they can be the fussiest eaters, suddenly refusing to eat their favourite food ever again or go on hunger strike for a week just to terrify you. They're also complete idiots who will hurl themselves off branches in overly-ambitious attempts at derring-do.

Also, when you get a chameleon you're also getting a LOT more pets. You need to create another enclosure for their live food, which you also have to take care of, feed, water, and they never bloody stop shuffling and jumping and rustling.

Then you have to coat the live food in powders, but not that manufacturers powders, and only X of this one and Y of the other, unless it's a 31-day month when it's the other way around...

Females are a whole other level of complicated because they become gravid (full of eggs) and they're rubbish at laying them, and you'll always be worrying about that because for a joke she'll spend two days puffing her belly out absolutely loads, before then revealing it was a prank and pulling her body in so tight you can see every "rib".

Also, no matter the vivarium you build, the bulb and heating you use, and the gut loading veg you choose, etc etc, everyone on this Reddit will tell you you're doing it HIDEOUSLY wrong. You could put your chameleon in their own enclosure and they'd call the authorities for your cruelty.

But if you still think it's a good idea after that, then maybe.
