Unable to set power button behaviour to 'interactive'

Hi, I am trying to change the power button behaviour on my Dell XPS 13 9380 to an interactive menu. This option doesn’t appear in GNOME settings and the dconf setting ‘/org/gnome/settings-daemon/plugins/power/power-button-action’ when changed to ‘interactive’ has no effect. My chassis is selected as ‘laptop’ and none of the various fixes from people with similar issues have been effective.

Many thanks!
