Mapbox GL js available icons

I am rewriting a web application from Mapbox.js to Mapbox GL js. Using the standard 'mapbox://styles/mapbox/streets-v8' style, where can I find a list of all working marker icons?

Here is my code:

m.map.addSource("markers", {
        "type": "geojson",
        "data": {
            "type": "FeatureCollection",
            "features": {
                "type": "Feature",
                "geometry": {
                    "type": "Point",
                    "coordinates": ["-75.532965", "35.248018"]
                },
                "properties": {
                    "title": "Start",
                    "marker-symbol": "entrance",
                    "marker-size": "small",
                    "marker-color": "#D90008"
                }
            }
        }
    });
    m.map.addLayer({
        "id": "markers",
        "type": "symbol",
        "source": "markers",
        "layout": {
            "icon-image": "{marker-symbol}-15", //but monument-15 works
            "text-field": "{title}",
            "text-font": ["Open Sans Semibold", "Arial Unicode MS Bold"],
            "text-offset": [0, -1.6],
            "text-anchor": "top"
        }
    });

I read that all Maki icons should be made available for styles that don't have icons as a default: https://github.com/mapbox/mapbox-gl-styles/issues/241 But most of them don't work. Also there is the problem with the sizes - for Maki they were -small, -medium and -large, and now I see -11 and -15.

I just need to use some basic marker icons.
