Manually opening / resurfaceing the consent layer
In order to allow users to later change their choices the CMP usually shows a preference-button (or recall-button) in the lower left corner of the window:
If you want the consent layer to show up (even for users that already gave consent), you can do so by simply loading the page with either a hash (
#cmpscreen) or parameter (
?cmpscreen). For example:
http://www.mywebsite.com/#cmpscreen will force the consent screen to show.
As an alternative you can use
?cmpscreencustom in order to show the custom choices page instead of the welcome page of the consent screen.
