showCloseButton
From SAP Enable Now Wiki
Scope
SAP Companion parameter, specified either in the URL or in the SAP Companion parameters in the linked application.
Purpose
If this parameter is set to true (which is the default as of Web Assistant 3.0.12) then a Close button is shown at the top of the 'Help Stripe'. The user can click on this button to close the Web Assistant (both the Carousel and the 'Help Stripe'). This is effectively the same as clicking on the Help button (?) again.
Usage
Specified as:
showCloseButton=true|false]
