LED flashes in the matrix when a button is pressed

[Welpi79]

I have an LED matrix with 24 LEDs.
In the LED setup, 24 buttons were assigned to these LEDs. If I now press button 1, LED 1 flashes as long as I hold the button.

Is it possible for the LED to only light up when I press the button?

I found a post here (#48 from September 8, 2020) where this flashing function was requested. Is it already implemented?

In the LED setup, under Functions, I only have Normal or Inverted.

Can anyone help me?
