Hi Kiran, I hope you're doing well!
The rapid IOT Prototyping kit can work as a Thread router, and has some blocks for configuring the device like so.
There's also compatibility and some blocks for connecting to AWS cloud services.
For reference, could you please take a look at the Rapid IoT Kit Out-Of-Box Demo? It can provide a better look on how to implement Thread Router Functionality. The demo application can be imported from the Rapid IoT Studio Demo Projects section.
Also, could you please take a look at the Getting Started guide for the Rapid IOT Prototyping Kit?
Please let me know if you need any more information.
Best regards,
Sebastian
