improve button (action control) appearance

One of our customers wants the button (action control, typically added in a text area) appearance to be improved.

For this use case the button is associated to an IronPython script that could take a while to run.

Regarding the behavior of the Action Control buttons, it's currently difficult to tell if a button has been pressed or not (especially in dark mode).

It would be more easy to use e.g. disble the button while executing, and restore it after it's done, not only tells that execution is in progress, but also can prevent the button from being clicked many times( all clicks are remembered and called subsequently)

When an IronPython script with a long processing time is assigned to a button, it's unclear whether it's actually executing.

The button's visual change when pressed is minimal; they hope this can be improved to make it more tactile / easy to read.

Furthermore, it would be even better if there were a standard feature option to display a notification (the bell icon) when a button is pressed.

For this, currently if we use notification service to show a message, it won't show up until the entire IronPython script is done.
