Hi @SUDHAN ETHIRAJ ,
Thank you for posting in this community.
In fact we are currently providing help on SharePoint in the Q&A forum, and Power Apps is a product independent of SharePoint which we are not so familiar with. So I suggest you start a new discussion in the Power Apps Community on this issue so that you can get more professional help, there will be very professional people to tell you the steps on how to realize this function.
