Apex SDK - Ability to configure ceremony settings

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();

                settings.ceremony = new  OneSpanAPIObjects.CeremonySettings();

                //return url set and button label

                settings.ceremony.handOver = new OneSpanAPIObjects.Link();

                settings.ceremony.handover.href = handover_url;

                settings.ceremony.handOver.text = 'Go back to application';

                settings.ceremony.handOver.title = 'Go back to application';

                //set the branding logo

                settings.ceremony.layout = new OneSpanAPIObjects.LayoutOptions();
