Cannot find WebViewContext for WkWebView on iOS Simulator with Appium - ios

Question

I currently have no access to the WKWebView via Appium. I start the driver with the following capabilities:
var options = new AppiumOptions();
options.AddAdditionalCapability("automationName", "XCUITest");
options.AddAdditionalCapability("platformName", "iOS");
options.AddAdditionalCapability("platformVersion", "15.5");
options.AddAdditionalCapability("deviceName", "iPad (5th generation)");
options.AddAdditionalCapability("language", "DE");
options.AddAdditionalCapability("app", "/Users/testautomatisierung/Projects/TestAppWebView/TestAppWebView/bin/iPhoneSimulator/Debug/device-builds/ipad6.4-15.5/TestAppWebView.app");
options.AddAdditionalCapability("derivedDataPath", "/Users/testautomatisierung/Library/Developer/Xcode/DerivedData/WebDriverAgent-ciegwgvxzxdrqthilmrmczmqvrgu");
options.AddAdditionalCapability("webviewConnectTimeout", "90000");
options.AddAdditionalCapability("safariLogAllCommunication", "true");
My Appium Server Logs tell me:
