[Inf-IT DAVcl] additional link to DAViCal admin page

Hello,

does a simple possibility exists for placing an icon with a link to the DAViCal admin page in CalDavZAP? Maybe below of the logout button?

I found an icon (images/banner_settings.svg) in the installation folder, which may be suited for this. But I assume this is dedicated for another purpose, maybe for the integration with CardDavMATE. With the actual version I can't discover, where and when it is used. But my Javascript and CSS knowledge is somewhat limited...
