User role or capability

Hi there,
great plugin! I need other users to be able to access and change the settings for the countdown bar. Atm only admins can see it. I’ve had a quick look through the plugin files, but can’t find any obvious mention to how you are limiting the functionality. Could you please help me by either telling me which capability to add to my other users, or which hook/filter I can use to let other users access the settings?
Kind regards,
Max
