Can I hide a button on the bottom right of the page?

After installing the plugin, beside a button where I put it, I notice there is another floating button on the bottom right of the page. I found the Display Floating Switch option in Settings which says “Enable Floating dark mode switch in frontend for toggling between dark and light mode” and I toggled it off. But the button is still there. How could I hide it? Because it conflicts with other buttons on my site.
