How do you set Accounting format in Google Script App?

[Brilstern]

In the function below, I am using column H to adjust the format of column F. I would like to adjust this format to an accounting format, but I am struggling to do so. Does anyone know how to convert this string, "USD":"[Red][$$]#,##0.00", to an accounting format in the Google Script App?

function onEdit(e){
 
    var sheetName = "Debt"; //name of sheet to adjust formatting on
    var currencyCol = 8; //column H
    var amountCol = 6; //column F
    var defaultFormat = "[$€]#,##0.00";
    var currencyFormat = {"USD":"[Red][$$]#,##0.00",
                          "GBP":"[Red][$£]#,##0.00",
                          "EUR":"[Red][$€]#,##0.00"};
 
    var r = e.range;
    if(e.source.getSheetName()==sheetName && r.getColumn() == currencyCol){ //edits one cell at a time
      var uf = currencyFormat[r.getValue()];
      uf = uf?uf:defaultFormat;
      r.offset(0,amountCol-currencyCol).setNumberFormat(uf);
    }
}
