Can you restore OpenStreetMap's attribution? (https://www.openstreetmap.org/copyright) or mention both?

    "base-raster": {
        type: "raster",
        tiles: ["https://tile.openstreetmap.org/{z}/{x}/{y}.png"],
        tileSize: 256,
        attribution: "<a href='/info' target='_blank'>MORE ABOUT ROADWAY.REPORT</a>"
    }
