Feat: Add application introduction slider

[devansh-299]

Summary:

We can add an introduction slider to the application to give basic insights into what the self-service application aims to provide to the users. These slides can also be used to ask for necessary permissions from the users for the functioning of the application

I would like to work on this but can you give a more clear idea about it . @devansh-299 do you want me to put some activities which will give the user a walkthrough of the application when he opens the application for the very first time?
