Hi @riabhatia24, thanks for your query and congrats on just getting your eye tracker!
The natural movements of the eye are such that the fine detail required to move a cursor in this fashion is not possible without additional software to help (or alternatively sufficiently large user interface controls to compensate).
Windows 10 now has Eye Control Features built-in since recent updates (did you try this already?) as well as other 3rd party solutions such as Xcessity, are available that allow full mouse control of your PC. Hopefully one of these will provide your needs.
Please let us know how you get on.
