## setTargetOrigin
Set the [window.postMessage API](https://developer.mozilla.org/en-US/docs/Web/API/Window/postMessage)
`targetOrigin`. The Vendure ui-devkit uses the postMessage API to
enable cross-frame and cross-origin communication between the ui extension code and the Admin UI
app. The `targetOrigin` is a security feature intended to provide control over where messages are sent.
