Hey if you want to edit the text, you have to locate the file where the text is found and find the text and replace it.
Other good way is Use https://code.visualstudio.com/ and open folder of script then from search search the text you want to replace, Visual Studio code will find the file where that text is and you can replace it.

1. Open folder of script in visual studio code.
2. Go to search so you can search in whole folder for string.
