Using ssh-add in 2k20's i3

It was suprisingly unwritten about workable configuration for the ssh-agent to use with i3wm. The following works for me after adding it to the ~/.profile and reloging in. 

case "$DESKTOP_SESSION" in
    i3)
    eval $(ssh-agent)
        ;;
    sway)
    eval $(ssh-agent)
        ;;
esac
