ACCESSIBLE VISITOR

Hello
Your plugin is good! Thank you for creating it and making it available for free.
However, make it on the wp-admin dashboard is fine.
But it is missing on the global site visitor side.
My question is :
Is it possible to put the button in “Night Mode” accessible for public-side visitors?
It would be superb.
Can you help me ?
I can pay, for this small customization.
Thank you
