How to capture the screen on mac using SwiftUI?

I am a beginner in SwiftUI. My task to capture the image of the whole screen using SwiftUI includes other apps and title bar. I am unable to show the permission dialog of screen recording and capturing the image of the screen. I have implemented the solution below but did not get success.

func screenshotWindowAndSuccess() -> Bool {

    let task = Process()
    task.launchPath  = "/usr/sbin/screencapture"
    task.arguments = ["-cm"]
    task.launch()
    task.waitUntilExit()
    let status = task.terminationStatus
    return status == 0
}

Please help me to get out of this task. Thank you in advance!
