Change label/text of Button - v7.4

I have created a simple snippet:

I am trying to dynamically change the text of the first button when I click on the second button. I have found several examples of this working when the button does NOT have an icon.

It seems like using an icon requires the use of “label”, which prevents setValue() or $setValue() from working.

Perfect! Thanks
