title: MS Teams : Initiate actions with messaging extensions still exists?
body: <p>According to Microsoft Documentation it is possible to initiate actions with messaging extensions 
  see <a href="https://docs.microsoft.com/en-us/microsoftteams/platform/concepts/messaging-extensions/create-extensions" rel="nofollow noreferrer">https://docs.microsoft.com/en-us/microsoftteams/platform/concepts/messaging-extensions/create-extensions</a></p>
  
  <p>To do so, the command must specify the "type" parameter with value "action" (MS example below)</p>
  
  <pre><code>"composeExtensions": [
      {
      "botId": "......",
      "canUpdateConfiguration": true,
      "commands": [
          {
            "id": "reassignTodo",
            "description": "Reassign a todo item",
            "title": "Create To Do",
            "type": "Action",
            "fetchTask": true
          }
      ]
  ]
  </code></pre>
  
  <p>But according to Microsoft Teams documentation "Reference: Manifest schema for Microsoft Teams" the "type" property doesn't exist !
  see <a href="https://docs.microsoft.com/en-us/microsoftteams/platform/resources/schema/manifest-schema" rel="nofollow noreferrer">https://docs.microsoft.com/en-us/microsoftteams/platform/resources/schema/manifest-schema</a></p>
  
  <p>BTW, import existing app in MS Teams fails !</p>
  
  <p>Is it a bug or, someone know why it disappears ?</p>
