[Solved] how to use QML or Qt to open a web URL using android's or IOS's native web browser

I am developing android/IOS SW using QML and Qt, and need to allow users to click on a web Url (or a related button) and then the SW immediately open a web browser like the native ones on android/IOS and show the content of this web Url. Could anyone tell me how to do this? Thanks! Look forward to your help!
