Come to think of it, you are re-inventing the wheel here!(*) You only
need one button with the script:

(ToggleDirective "chord" "postfix" (cons "Tremolo" "𝅬") ":32 ")


You also had a move in your script - you could add that too - you might
want to test if you have just deleted or installed a tremolo (if you
have deleted it then (d-Directive-chord? "Tremolo") is false).

(*)I looked this up in the Manual, and it is no wonder you wouldn't find
it, or how to use it. I had to look up the file
actions/denemo-modules/directives.scm to find the instructions on how to
use this, and even then it is spread over this and the AttachDirectiv
procedure comments. (ToggleDirective calls AttachDirective).
