Command to remove an indicator from a button.

New comment
 
Hello !
I need help, I have an indicator that I want to place a button on that  when pressed, the indicator will be completely eliminated. Can you help me? I only need the command to remove the indicator, the rest is already done.The only thing missing is its button (I'll create it) to remove the indicator and the function or code to remove the indicator.
