react-google-maps align MarkerWithLabel horizontally

I want to create a marker with a label above, and later on make it so I can click the marker and it opens up info boxes. I have:

<MarkerWithLabel labelAnchor={{x: 0, y: 25}} icon={marker_icons[post.type]} key={post.id} position={{lat: post.location.lat, lng: post.location.lon}}>
    <div style={{fontSize: 14}}>{post.prefix + " " + post.name}</div>
</MarkerWithLabel>

Currently it looks like the left but I want to align the label to look like the right one, how would I be able to do that?

To align label the following option could be considered:

• specify label container (div) width and set text-align to center via labelStyle property
• set labelAnchor property based on label container width

The following example displays label on top of marker and label content vertically aligned to center

const Map = (props) => {

    const labelSize = { width: 220};
    const labelPadding = 8;

    return (
      <GoogleMap 
        defaultZoom={props.zoom}
        defaultCenter={props.center}
      >
        {props.places.map(place => {
          return (
            <MarkerWithLabel
              labelStyle={{ textAlign: "center", width:labelSize.width + 'px', backgroundColor: "#7fffd4", fontSize: "14px", padding:  labelPadding + "px"}}
              labelAnchor={{ x: (labelSize.width/2) + labelPadding , y: 80 }}
              key={place.id}
              position={{ lat: place.lat, lng: place.lng }}>
              <span>{place.name}</span>
            </MarkerWithLabel>
          );
        })}
      </GoogleMap>
    );
}
