Rotor braille Items Question for iOS 15.2

Hello,

I recently found 5 new available rotor items, but I don’t have any clue what they mean. They are as follows.

• Braille Zoom

• Braille Thickness

• Braille Horizontal Pan

• Braille Vertical Pan

• Invert Braille

Does anyone have any information? I’m running iOS 15.2 on an iPhone 11 Pro Max. I enabled all of these new rotor items this morning and connected my Mantis Q40 to my iPhone. I looked through the rotor on the home screen, in the phone app and in the photos app. I could not find the new items I'm asking about anywhere when I cycled through the rotor options. Thank you!
