Text Based Config use of Material design icons in dashboard


the following config is not allowed via text based config:

           "columns": 8,
           "rows": 5,
                   "label": "openHAB",
                   "icon": "mdi:floor-plan",

the mdi:floor-plan icon is not working as dashboard icon.

@rene54321 do you have Material Design icons enabled in settings in the app?
