Are you using the map component? There aren’t any iframes to embed at all. The markers you’ll add inside the post on the right hand side, not within Mapbox. Mapbox is ONLY showing the map tiles.
Here are some docs on how to use this component:

If you want to use the markers from mapbox you’ll need to use their embed code.
