Hello @adarshumangraj6,
First of all thank you for using our theme.
To place the widget in the front page widget area goto Admin Panel > Appearance > widgets. There you will be able to see the front page widget area where you can place the widget of your choice .
After the placement of the widget at the backend, you will be able to see Front Page Widget area in Admin Panel > Appearance > Customize > Widgets as well.
Hope this helps.
Also if you have any issue further, we are always there for you.
Best Regards!!
