Thanks. Although gnome-shell, snapd and deja-dup-monitor are the top users for the previous 60 seconds, it also shows that snapd has used an accumulated 4m40s which is way above everything else.
Given your uptime is 5h34m then that means snapd has used an average of over 1% of your CPU for that entire uptime. So I think snapd is the next thing to look at.

Please try disabling snapd for a while:
sudo systemctl stop snapd.socket
sudo systemctl stop snapd.service
Again leave the desktop idle, and tell us if that has improved the power use.
