Is there any way that style of [daq.LEDDisplay] be rendered through className?

AS documented in [leddisplay-properties](https://dash.plotly.com/dash-daq/leddisplay#leddisplay-properties)

className (string ; optional): Class to apply to the root component element.

Though root component’s style is rendered by className, color and background-color in LEDDisplay are not subject to className.

For example, a daq.LEDDisplay component is constructed like this:
leddisplay
code:

        html.Div(
            className="card-elem",
            id="total",
            children=[
                  daq.LEDDisplay(
                       label="total",
                       labelPosition="bottom",
                       value="110",
                       size=20,
                       className="LEDDisplay",
                )
            ],
        )

className="card-elem" and className="LEDDisplay" properties are defined in css:

.card-elem {
  width: 5rem;
  border-radius: 8px;
  margin: 3px;
  padding: 3px;
  font-size: 1rem;
  background-color:#e9ecef38;
  box-shadow: 2px 2px 2px lightgrey;
}
.card-elem .LEDDisplay {
  display: inline-block;
  color: #F6F6F6;
  background-color: #008ed4;
}

The css style dosen’t work in daq.LEDDisplay. Is there any way to define LEDDisplay’s style through classname?
