Hi! @armagandalkiran, @aahmetcakir!

I've observed that there's a modal designed for updating user nicknames. However, we have the opportunity to enhance its dynamism. By utilizing ContextAPI, we can manage this modal using just one instance. Currently, the modal lacks confirm or cancel buttons, but we can incorporate them in the future and manage their functionality through custom onConfirm and onCancel functions.

Let me illustrate this with a simple API example:

Despite the current absence of proper confirm and cancel buttons in the design, we can utilize a custom closeModal function to close the modal once the associated logic is completed.

And you can assign it to me if you want. 🚀

We did not open issue about the popup yet so if you would like to implement this behavior you are more then welcome to do it. After this implementation done we can open issue about the implementation of nickname change popup. Of course i can assign it to you if you want to do it 🚀
