Read the documentation.

JavaScript

async function init() {
    const { AltitudeMode, Map3DElement, Marker3DInteractiveElement, MapMode, PopoverElement } = await google.maps.importLibrary("maps3d");
    const map = new Map3DElement({
        center: { lat: 37.8204, lng: -122.4783, altitude: 0.407 }, range: 4000, tilt: 74, heading: 38,
        mode: MapMode.HYBRID,
    });
    // Popovers can only be added to interactive Markers
    const interactiveMarker = new Marker3DInteractiveElement({
        altitudeMode: AltitudeMode.ABSOLUTE,
        position: { lat: 37.819852, lng: -122.478549, altitude: 100 }
    });
    const popover = new PopoverElement({
        open: false,
        positionAnchor: interactiveMarker,
    });
    popover.append('Golden Gate Bridge');
    interactiveMarker.addEventListener('gmp-click', (event) => {
        // toggle the marker to the other state (unlee you are clicking on the marker itself when it reopens it)
        popover.open = !popover.open;
    });
    map.append(interactiveMarker);
    map.append(popover);
    document.body.append(map);
}
init();
