React-native ios app "back" handle

I am using appium for testing my react-native application in “iOS” environment,
and i have a case where I have to go back from screen in Android I have used “driver.back() annd driver.presskeycode(4)” and that worked fine

but in ios it is not working is there any method that i am missing in docs? to go back from one screen to backscreen.(stack navigation)

in image I have marked back button i want to press it and it is a symball so i can not select it with xpath or any other id selector…

Appium can handle symbols. If you look at this screen in Appium Inspector, you should be able to copy the symbol and look for it with your preferred method in your code.
