Set visibility of a layer when app opens to off

[MarquesMunson1]

Is there a way that I can set the initial visibility of a layer on the layerlist widget to off when the application loads? Then the user can choose to turn the layer on, if needed. I am in the configs LayerList json file. I believe that is where the adjustment is made but I am not exactly sure what to put. Any help is greatly appreciated! Thanks!

You can turn off the visibility of the layer in the original web map.

thanks so much! I thought there had to be some type of code to write.
