How to enable the "Auto Resize" function under the preferences and "Regional Text Options"?

I want to activate two functions of text:
One is:
Preferences>Text>Automatically adjust the text size in the new area“

The second one is the menu:

"Text>>Regional Text Options>Auto Resize“

I have searched a lot of information but have not been successful, and it seems that I can only open the preferences option.
A single text object cannot be set, which is a bit unscientific.

function setAutoTextFrames() {
    //var autoSize = app.preferences.getBooleanPreference("text/autoSizing");
    //app.preferences.setBooleanPreference("text/autoSizing", true);

    var autoSize = app.preferences.getStringPreference('text/autoSizing');
    alert(autoSize);

}
setAutoTextFrames();
