appium is necessary for Katalon Studio

can anyone explain appium is necessary for Katalon Studio

Because it is a framework used for mobile automation. Katalon Studio built-in keywords are wrapped up from Appium functions, so without Appium you can’t do mobile testing.

when i try to install appium then why it show me this error
