Welcome to the forums! 🥳
Buttonizer actually shows the button on the mobile based on the width of the screen.
So making the browser window on desktop smaller, to 769px, will make the button appear.
It might be a great idea to make the button only appear on mobile devices. 🤔
I'll add this into our feature request list and we'll take a look at it in the future. 😀
If you have any questions, please let me know!
We'll be happy to help!
