App Lab autofocus

I’m trying to find a way for a text input to be selected automatically when an app in App Lab runs. There is an HTML option for autofocus that accomplishes this, and I’ve tried plugging it in to setStyle as a CSS option, but can’t get it to work. Does anybody know a way to make this happen or a clever workaround? Thanks for your help!

I don’t think this can be done in AppLab. This question has been forwarded to the team for confirmation. Someone will post here if this is a possibility.
