Add / Remove Users in Firebase Authenticate

Is there any possible way to add or delete users through the app only to manage the users without playing with firebase or the block code ?

https://firebase.google.com/docs/reference/rest/auth#section-delete-account

I checked that link, but how can i manage Multiple Users froma single admin user. i.e. The admin can add or remove users from the app and app itself. Can you help me the blocks.
