Creating whatsapp client in thunkable app inventor

I want to make a whatsapp web client for android using thunkable app inventor but in webview whenever I try to add the url web.whatsapp.com, it redirects me to whatsapp.com please help me if anyone knows the solution. Btw I am making this client so that I don't need to see ads from the others clients available on play store cuz I have two phones and I need whatsapp on both of them but whatsapp doesn't allow it.

Thanks
