Add a border to my Touchbar buttons


is it possible to add a colored border on my customized touchbar's buttons ?

If yes, can you tell me how to do it, please ?


Unfortunately BTT can't add borders. The only workaround would be to assign an icon that has the full size of the button.

Thank you for your work and your answer, Andreas.

I'll try to make my icons including the whole button, in this case !
