RCS Webviews are now supported

Twilio now supports sending webviews on RCS through twilio/card. 

Webviews are new way for your customers to open links that keep them on the messaging thread. With webviews through Twilio, you can designate the height of the in-app browser that opens the webview. 

Additionally, webviews opens the door for more even richer interactions through RCS with integrations such as boarding passes and in-messaging payments.
