css - Place a div above InfoWindow?

Question

I'm trying to place a div above InfoWindow component from google-maps-react. I tried my code below but the InfoWindow isn't appearing :

<div>
            <div className={styles.superdiv}>
              <img
                src="/svg/e.svg"
                alt=""
                height="26"
                width="26"
                className="mr-2"
              />
              <span className={styles.superDiv}>SuperDiv</span>
            </div>
            <InfoWindow
              marker={activeMarker}
              onClose={onInfoWindowClose}
              visible={showingInfoWindow}
            >
              <div className={styles.infoWindow}>
                <p className={`m-0 ${styles.city}`}>city</p>
              </div>
            </InfoWindow>
          </div>

.superdiv{
    position: relative;
}
