📄️ Web
Embedding the iframe in a regular web page is the most common scenario. You drop an ` tag into your markup and listen for messages on window`.
📄️ iOS
On iOS the iframe communicates with the host application through the webkit bridge. Configure a WKWebView with a script-message handler named bridge and decode the JSON string the iframe posts.
📄️ Android
On Android the iframe communicates with the host application through an injected JavaScript object called legitHealthJsObject. Use WebViewCompat.postWebMessage to wire it up.
