I am trying to add more than one ControlWidget in iOS 18 and I get an error and not sure whether I am doing anything wrong or there is a bug (or maybe it's not supported by design?) I get the following error: encountered an error: Error Domain=com.apple.dt.deviceprocesscontrolservice Code=8 "Failed to show Widget 'check.ios18-test.intent-ext-ui' error: Error Domain=FBSOpenApplicationServiceErrorDomain Code=1 "The request to open "com.apple.springboard" failed."
