You can download zip file from https://abhinavhanda23.gdy.club/abc.zip and go to examples and edit two-geocoders.html file. The following line will set your view:
var map = L.map('map').setView([30.85879, 75.86304], 16);
Just by changing longitude and latitude and zoom level you will get your required view. OR You can get Leaflet search control that uses OpenCage Data’s geocode from this link , after this you need to change default location of your map which can be done by changing longitudes,latitudes and zoom level.
