I solved this issue by creating my own tooltip:

const Handle = Slider.Handle;

const handle = (props) => {
      const { value, dragging, index, ...restProps } = props;
      return (
         <Handle value={value} {...restProps}>
            <div className="inner">
               <div className={`wdc-tooltip${dragging ? ' active' : ''}`}>
                  <span className="wdc-tooltip-inner">{value}</span>
               </div>
            </div>
         </Handle>
      );
};

and rendering the component like this:

<Slider
   step="10"
   handle={handle}
/>

You will need to add some css to style it, and no need for using other components such as <Tooltip>

here's my scss:

.wdc-tooltip {
    position: absolute;
    top: 0;
    left: 50%;
    transform: translate(-50%, -100%);
    z-index: 9999;
    font-size: 10px;
    line-height: 1.5;
    opacity: 0.9;
    user-select: none;
    visibility: hidden;
    opacity: 0;
    transition: all ease-in-out 150ms;
    &.active {
        visibility: visible;
        opacity: 1;
        top: -10px;
    }
    span {
        display: block;
        text-align: center;
        color: #fff;
        text-decoration: none;
        background-color: #373737;
        border-radius: 5px;
        box-shadow: 0 0 4px rgba(0, 0, 0, 0.17);
        position: relative;
        font-weight: bold;
        user-select: none;
        padding: 5px 10px;
        &:after {
            content: '';
            position: absolute;
            width: 0;
            height: 0;
            border-color: transparent;
            border-style: solid;
            border-width: 5px 5px 0;
            border-top-color: #373737;
            left: 50%;
            bottom: 0;
            transform: translate(-50%, 100%);
        }
    }
}
