Double handle slider

Hi everyone,
I am trying to program a 2 handle Spectrum Slider without success.
Is it possible to do on a vanilla plugin?

import ‘@spectrum-web-components/slider/sp-slider.js’;
import ‘@spectrum-web-components/slider/sp-slider-handle.js’;

The import statements generates the following error and I have only one handle :
./index.js:9 Uncaught SyntaxError: Cannot use import statement outside a module

<div class="spectrum-Slider" style="position: absolute; top: 150px; left: 5px; width: 200px;">

<sp-slider variant="range" step="1" min="0" max="255">
    Output Levels
    <sp-slider-handle
        slot="handle"
        name="min"
        label="Minimum"
        value="5"
    ></sp-slider-handle>
    <sp-slider-handle
        slot="handle"
        name="max"
        label="Maximum"
        value="250"
    ></sp-slider-handle>
</sp-slider>

</div>

Any help will be greatly appreciated

This might give you a hint why you’re out of luck

Thank you very much, i’ll try something that can be handled by jquery.css or something else.
