I’m really looking forward to someday either Ilya or the Clear team to share the link to unlock this icon.
Just out of curiosity, what is it about that icon that you enjoy so much?
I like the volumetric tick in this icon that shines on a dark background. And I use a dark version of icons in iOS 18 for this period, and this icon would perfectly complement my setting.
Good luck and I hope you get it!
