I add dynamically zoom to a Mapcomponent webmap (API 4.33) with:
const zoom = document.createElement("arcgis-zoom");
mapDiv.appendChild(zoom);
The buttons need to be bigger. Figured that out but how can I increase the size of the + and - symbol inside the standard button. Spend hours of searching in the online documentation, used AI but I have no working solution. Has something to do with a shadow dome I suppose.
