Accessibility issue with “Powered by…” text

Hi there. The slide-in is getting flagged up by Page Speed Insights for inappropriately sized tap targets – it’s the line at the bottom: “Powered by Usercentrics Consent Management”

I tried to target it in my custom CSS, but it’s not taking any notice (the classes are all random characters, which doesn’t help, although I did my best to copy-paste and get specific).

Is there a way to target this text/link beyond custom CSS? All I want to do is increase the font size to 1em and add a little top/bottom padding.

Thanks
