Is it possible to retrieve area icons?

I created some custom cards using decluttering, mushroom and button-card. Some of the cards are related to areas/rooms. I didn’t find a way to retrieve the icons which are configured by area, so I am using some templating to get ‘dynamic’ icons for each area.
It would be great if we can use the already available area icons. Unfortunately the is no area_icon(‘Living room’) option available. Does anyone have any ideas on how to make this happen?

I do not think there is an official way. Suggest to create a FR to add a template extension.
