React Native on Appium Studio

Hi all, I have developed some test cases for a react native app on appium studio, everything is fine if I run it via appium studio. But if I run my test cases on appium (not appium studio), the test cases will failed due to element not found. I realised that there is a instrumentApp=true in the capability settings and it is not included in Appium official documents. My question is how appium studio handle this capability ?

dc.setCapability(“instrumentApp”, true);
