Authentication dialog triggered by URLExecute in Wolfram player does not allow me to type in username/password

I have exploration tool that reaches out to elasticsearch for data from a Manipulate call. The idea is to share a notebook with some support folk and they can select customers and some parameters and get graphs and tables back and make decisions based on that.

The tool works by making a URLExecute call to an internal elasticsearch cluster. In Mathematica proper it pops up an authentication dialog and remembers username and password for the duration of the session.

When I run this in the player, I get the dialog but it doesn’t let me to type anything into the boxes for username/password.

Any idea what gives here? If this is not supported by the player, I wonder why there is a dialog in the first place…
