WebView Removed from vRO

Hi All

I have a workflow that uses send interaction to get approval by mail.

The workflows works fine on vCO 5.5.

I recently migrated it to vRO 6.0 and following is the error I get.

Wrapped java.lang.RuntimeException: WebView are removed since 6.0. getAnswerUrl() is no longer valid (Workflow:Send interaction / Send Email with User Interact (item0)#3)

I understand WebView has been removed from 6.0 onwards but what is the alternative if any that has been introduced.

Thanks in Advance
