AWS managed policies

     "Statement": [
          {
               "Sid": "VisualEditor0",
               "Effect": "Allow",
               "Action": "lex:List",
               "Action": "lex:Describe",
               "Action": "lex:StartConversation",
               "Resource": "*"
          }
    ]
}
