ceremony

I am trying to use ceremony settings in salesforce to customize various options, but they do not seem to render.

Please help me understand what i am missing. I could not find appropriate documentation for each node.

You will see event if i am setting session bar as true, it still does not show up
Also, setting up background color and color has no effect.

Logo is too big.

Here below is settings I am using:

OneSpanAPIObjects.Settings settings= new OneSpanAPIObjects.Settings();
