How to modify the spinning circle icon next to the script name to a specific value

How to modify the spinning circle icon next to the script name to a specific value, such as "running," and display it in red font. The reason for wanting to modify it is that the spinning circle causes eye discomfort. Could a kind person please tell me the specific location of the code related to this icon?
