WMS Geoserver

I want to add a GeoServer WMS to a modern web application. In which part do I need to make adjustments? Do I need to make adjustments on the server as well, or is it only necessary on the web application?

Web app should be enough.

I want to implement the following URL:

http://localhost:8080/geoserver/wms?service=WMS&version=1.1.0&request=GetMap&layers=tasmania&bbox=143.83482400000003%2C-43.648056%2C148.47914100000003%2C-39.573891&width=768&height=673&srs=EPSG%3A4326&styles=&format=image%2Fpng

In which file should I add the above URL? Is it in the useMapStyles.js file?
