Downloading Updates In-Game

Hi, I would like to be able to open my game, and tell players that there is an update, then they can click “Update game” and then it will update, and then proceed to tell them that they need to restart their game to Use the newly downloaded update. How can I download from something like Google Drive or Github, and download it to the right place? I need to do this all in blueprints. Please help!!! Thanks!
