How Can I Dynamically Create []*waProto.ButtonsMessage_Button From A List Of Records?

[rvp98]

msg = &waProto.Message{ButtonsMessage: &waProto.ButtonsMessage{
		HeaderType:  waProto.ButtonsMessage_EMPTY.Enum(),
		ContentText: proto.String(rc.Respond),
		FooterText:  proto.String("Gunakan tombol di bawah ini untuk memilih keyword yang anda butuhkan"),
		Buttons: []*waProto.ButtonsMessage_Button{
			for i := range arrBtn {
				fmt.Println("Button Title", arrBtn[i].ButtonTitle)
				{
					ButtonId: proto.String(arrBtn[i].ButtonId),
					ButtonText: &waProto.ButtonsMessage_Button_ButtonText{
						DisplayText: proto.String(arrBtn[i].ButtonKeyword),
					},
					Type: waProto.ButtonsMessage_Button_RESPONSE.Enum(),
				},
			}
		},
}}

I know this is a wrong way, and im new to GO. But i need something like this :(
