Turn off your car. Within a few seconds, press up (counterclockwise) on the wiper control lever and they'll sweep up and stop in their fully-counterclockwise position. Then you can lift them off the glass the usual way.
To put them back to normal, make sure the wipers are back down against the glass, turn the car back on, and set the wiper lever to any of its operating settings.
It's a shame this is buried on pages 246-7 of the 2021 Camry's manual!
But I should point out that I rented a non-electric Chevy Volt (they do exist) and had to go just about as deep into its manual to figure out how to open the door over the gas filler cap at the gas station - it's controlled by a lever on the floor! And it's a "stealth" four-door car: the door handles for the rear doors are hidden up at the roof-line. I only found them when I was unable to tilt the driver's seat forward to let a passenger into the back seat!
It's a shame there's no review of these obese operating manuals to put often-needed information like this up front!
