The goal is to be able to do the same in LCW => something like:

adaptivecard sent by PVA :

{

  "type": "AdaptiveCard",

  "version": "1.0",

  "actions": [

   {

    "type": "Action.Submit",

    "id": "clickMe",

    "title": "Click me!"

   }

  ]

}

On website client side with LCW 2.0:

window.addEventListener("lcw:onExecuteAction ", function (action) {

})
