Cant pass ios spectific fields through FCM

Hi!
I have a problem. I try to pass "alert" field through FCM.
As far as I understand FCM works both for ios and android but for go rush its like "android mode".
And i need to pass ios specific field alert through him like this

{

  "notifications": [

    {

      "tokens": ["123"],

      "platform": 2,

      "message": "Ground control to major Tom",

				"alert": {

					"title" : "Game Request",

					"body" : "Bob wants to play poker",

					"action-loc-key" : "PLAY"

      }

		}

  ]

}

Is it possible? I pass platform = 2 because it FCM

No file or test is named in the issue. Start by locating the FCM handling path for platform 2 and compare the accepted notification fields with the shown iOS alert payload; done means establishing whether alert can be passed through and capturing the supported behavior in a test or documentation.
