            {/* <div className='salesRibbon__productCarousel_forHidden' id='salesRibbon__productCarousel_forHidden'> */}
                <ScrollContainer className='salesRibbon__productCarousel' ref={container} vertical={false}>
                    {sales.map((data) => {
                        return(
                            <ErrorBoundary>
                                <ProductPlate key={data.id} sales={data}/>
                                <ProductPlate key={data.id} sales={data}/>
                                <ProductPlate key={data.id} sales={data}/>
                                <ProductPlate key={data.id} sales={data}/>
                                <ProductPlate key={data.id} sales={data}/>
                            </ErrorBoundary>
                        )
                        })
                    }
                </ScrollContainer>

    )
}

<div className='salesRibbon__arrows_arrowForward' onClick={() => document.getElementById('container').scrollLeft += 20}> <— this bloddy doesn’t working as well

    INSTEAD

    <ScrollContainer className='salesRibbon__productCarousel' ref={container} vertical={false}>

    DO

    <ScrollContainer className='salesRibbon__productCarousel' innerRef={container} vertical={false}>

    change ref to innerRef

    Here is an example of how your ScrollContainer would receive the reference. Click on the broken image links and you will see the scroll value in the console:

    const images = {
  salesRibbon__arrowBack: "",
  salesRibbon__arrowForward: ""
};

const ScrollContainer = React.forwardRef((props, container) => (
  <div ref={container}></div>
))

const SalesRibbon = () => {
  const container = React.useRef(null);

  const scroll = (scrollOffset) => {
    container.current.scrollLeft += scrollOffset;
    console.log("scrolled", scrollOffset);
  };

  return (
    <React.Fragment>
      <div className="salesRibbon__arrows">
        <div
          className="salesRibbon__arrows_arrowBack"
          onClick={() => scroll(-20)}
        >
          <div className="salesRibbon__arrowBack-gradient"></div>
          <img
            className="salesRibbon__arrowBack-arrow"
            src={images.salesRibbon__arrowBack}
            alt="Стрілочка вліво"
          />
        </div>
        <div
          className="salesRibbon__arrows_arrowForward"
          onClick={() => scroll(20)}
        >
          <div className="salesRibbon__arrowForward-gradient"></div>
          <img
            className="salesRibbon__arrowForward-arrow"
            src={images.salesRibbon__arrowForward}
            alt="Стрілочка вправо"
          />
        </div>
      </div>
      <ScrollContainer
        className="salesRibbon__productCarousel"
        ref={container}
        vertical={false}
      ></ScrollContainer>
    </React.Fragment>
  );
};

ReactDOM.createRoot(document.getElementById("root")).render(<SalesRibbon />);
