SharePoint list formatting extended title with icon in calendar view

[MGNFC]

Is it possible to expand the display of the element in the calendar view by an icon depending on the selection in a column?

In the Column View it was no problem, but to map the same on the Calendar View i have not been able to do it. Does anyone have an idea ?

            "style": {
              "padding-right": "5px",
              "display": "=if(indexOf([$Type], 'Workshop') != -1, 'flex', 'none')",
              "color": "=[@theme.palette.themePrimary]"
            },
            "attributes": {
              "iconName": "Add"
            }
          }
        ]
      },
      {
        "elmType": "span",
        "txtContent": "[$Title]"
      }
