new IPhone need help learning how to use with braille sense

Hello, I am new to the forum, and up till now, I have always used Windows computer. I wanted to take advantage of all the features I could use braille with. Translating all the lessons I am learning about voiceover into braille is very hard for me, was wondering if someone would spend a little time just kind of helping me set things up and learning how to basically move around screen and apps and explain the rotor better to me and how it relates to what the braille display is doing. Got it paired, but now at a loss. Not many tutorials to show how things are done with braille. I am using the screen tapping as little as possible as my hands shake so it's hard to do. If anyone wants to do a phone call with a little help, I'd be so grateful. I usually do well after I get a jumping off point, but I am feeling a little stuck with all the new Apple concepts even though I am taking a class.
