Good afternoon! I use the library to react-google-maps. How can I get the coordinates of the center of the map?

I use the library react-google-maps. The coordinates can be obtained with getCenter(), but I can not. How to make a button in the component that will send the coordinates of the center to the parent function and how to get these coordinates from the center? Can you know? Thank you!

react-google-maps

getCenter()

const Map = compose( withProps({ googleMapURL: "https://maps.googleapis.com/maps/api/js?key=AIzaSyB8ECfIjkNyE2AVBlG4Fpd4rD2Y4q5Ytpk", loadingElement:

,
        containerElement:

,
        mapElement:

,
    }),
    lifecycle({
        componentDidMount() {
            const refs = {}

            this.setState({
                onMapMounted: ref => {
                    refs.map = ref;
                    console.log(refs.map.getCenter())
                },
            })
        },
    }),
    withScriptjs,
    withGoogleMap
)((props) =>
    
        {markers.map( function (obj, index) {
            return (


                    
                        {props.isOpen &&
                            
                                 
                                     {obj.title}
                                

                            </InfoWindow>
                        }
                    </Marker>
                </div>
            );
