Webview on Facebook Messenger returns user id after button template but not after permanent menu button

Question

Webview on Facebook Messenger returns user id after button template but not after permanent menu button

When I generate this template, I get the user id in the webview:

{
  "message" : {
      "attachment" : {
          "type" : "template", 
          "payload" : {
              "template_type" : "button", 
              "text" : "webview test", 
              "buttons" : [
                  {
                      "type" : "web_url", 
                      "url" : "...", 
                      "title" : "open", 
                      "webview_height_ratio" : "full", 
                      "messenger_extensions" : true
                  }
              ]
          }
      }
  }
}

Run code Hide result

But when I try to access the same webview through the persistent menu, I get the error: This SDK method is not supported by this Messenger client. Refresh the page.

I posted this on Facebook Api to set the menu:

{
  "persistent_menu":[
    {
      "locale":"default",
      "composer_input_disabled":false,
      "call_to_actions":[
	        {
	          "type":"web_url",
	          "title":"Instellingen",
	          "url":"###URL###",
	          "webview_height_ratio":"full",
	          "messenger_extensions": true
	        }
    	]
    }
  ]
}
