Is there a way to open the app in a larger window?

I’m trying to build an app using the reactjs quickstart-workdocs template. When I was testing out the app from the context menu it opens in a smaller window. I would see if is possible to make the app container window bit larger. Is there a way to resize the heigh and width using css or inside reactjs code? I tried overwriting the ifram’s parent divs’ css but seems to not effecting it.

  1. which type of app or app feature gives access to the entire workdoc content. The context menu or item feature seems to only give access to the current itemblock content.
