[New Content]: Adding Reown as one of the toolings deployed on Scroll

[rohit-710]

What would you like us to add?

Reown provides open source and free to use SDKs for both Web3 apps and Web3 wallets. A high level overview of this needs to be added.

How important it is?

It's fairly important as it allows users to provide end-to-end wallet interactions for their Web3 app built on Scroll.
