Does Mappls Web SDK have a specific property to set the initial zoom level of the map view upon loading?

Yes, the zoom property is used to control the initial zoom level of the Mappls map. When initializing the map, you can specify the zoom level in the configuration object.
For example:
map = new Mappls.Map(‘map’, { center: { lat: 28.612964, lng: 77.229463 }, zoom: 10 });
This sets the initial zoom level of the map to 10.
