By the way the extension or settings up the value doesn't change the brightness. Any help regarding this would be appreciated.
Btw, change in actual_brightness also doesn't make any changes.

The extension can't work on a PW4 because the contents of /sys/class/backlight/ are different, that is why I asked, because I do not have a PW4. Also, please use text instead of a photograph or at least use a screenshot. You can use the "screenshot" command in the terminal or tap 2 diagonal corners of the display.
When you did the echo > 1 command, did the screen get dim?
If not, there is nothing you can do.
If it does get dim, you can change all instances of max77696-bl in the script to bl.
/sys/class/backlight/actual_brightness is readonly. You can't change it.
You can save text output from a command like this:
ls -l /sys/class/backlight/ >> /mnt/us/command_out.txt
Then you can copy command_out.txt to your PC.
