Welcome to the forum! 
Either your laptop manufacturer included battery charging limit support or they didn’t. If it does, then it’s up to the kernel to detect it. Nothing to do with the Desktop Environment.
Please post your system info as outlined here:
Please also see:
What’s the output of:
ls /sys/class/power_supply/BAT1 | grep charge
If there is support, then you should see output like I see on my System76 Gazelle (gaze17-3060-b) :
charge_control_end_threshold
charge_control_start_threshold
charge_full
charge_full_design
charge_now
