I added a PR to include a few examples for this. Hope it helps.

i can create and render a marker on the map with the usual example from mapbox docs on react, like
let marker
marker = new mapboxgl.Marker().setLngLat(geolocation).addTo(map.current);
but i cannot use/access the new marker variable and functions outside of the scopes, even directly on the component block itself

@sabasm can you describe more about what you wanted to achieve with the marker? :)
