Issues with brightness control on i3wm ( in built keys shortcuts )

I am using a HP laptop where the system itself has a key assigned to shortcut for brightness, volume and baclit keyboard.
Everything is working fine except the brightness, what can I do to use the keyboard keys and not every time open terminal and use xrandr.

This is how audio looks when I use the keyboard shortcut

This is how the brightness looks, empty:

I want to use the inbuilt keyboard bindings for more easier control to brightness.
Overall I find this OS is the best Arch based distro for everything. Brightness is the only thing that is pain in the @$$

Try this:

bindsym XF86MonBrightnessUp exec brightnessctl -c backlight set +5%
bindsym XF86MonBrightnessDown exec brightnessctl -c backlight set 5%-

Brightnessctl is in extra.

Other options are light & xorg-xbacklight which off course have their own syntax. The problem with these keys is they are hardwired in the bios, so you might not get anything to work.
