Edited a dashboard to hide controls, and used wall paper to go full screen

Good evening
used wall paper to hide controls and used panel to go full screen
but i cannot seem now to edit the screen to alter the panel
anyway of doing this now ?

my bad right at the bottom has instructions
" After hiding the toolbar, I can no longer edit the dashboard. How can I recover?

If you add ?edit=1 or ?wp_enabled=false to the URL in the browser, wallpanel will not be active, so the toolbar will not be hidden either. You can also use ?wp_hide_toolbar=false to only change this setting."
