question

I am new to this so I am trying to grasp the correct way to do this. I am trying to search through the player inventory for a specific item to get the InstanceId. Then use the InstanceId with the ConsumeItem command.

	public void ConsumePotion() {
		PlayFabClientAPI.ConsumeItem(new ConsumeItemRequest {
			ConsumeCount = 1,
			// This is a hex-string value from the GetUserInventory result
			ItemInstanceId = "How do i get this Value?"


		}, LogSuccess, LogFailure);


	}

I can get the values but I don't know how to use them

	public void GetInventory() 
	{
		PlayFabClientAPI.GetUserInventory(new GetUserInventoryRequest(),OnGetInventory,error => Debug.LogError(error.GenerateErrorReport()));
	}
	public void OnGetInventory(GetUserInventoryResult result)
	{
		Debug.Log ("Received the following items:");
		foreach (var eachItem in result.Inventory) {


			ItemIds.Add (eachItem.ItemId, eachItem.ItemInstanceId);
			string Instance = ItemIds [eachItem.ItemId];
			Debug.Log(Instance);
		}


	}
