Reading iMessage without having Apple device

Hi, I have an old Apple account as I owned Apple products in the past and now I am all PC and Samsung. Recently my daughter got a new iPad from her father to be used at our house for communication (divorced). I've set it up with Parental controls using my Apple Account. I would like to use app approval but the approvals are sent via iMessage that I have no way of reading. There is no Web interface for them as far as I know. I had to switch off the app approval all together.
