C++/Flatbuffers - Verify table which is not root_type

Question

Here is my fbs:

namespace Vibranium;

enum LOGIN_STATUS : int {
  INVALID_CREDENTIALS,
  LOGIN_SUCCESS,
  ACCOUNT_LOGGEDIN,
  ACCOUNT_INGAME,
  ACCOUNT_BANNED,
  ACCOUNT_LOCKED
}

table LoginRequest{
    email:string;
    password:string;
    client_hash:string;
    connection_id:uint32;
}

table LoginResponse{
    account_id:uint32;
    status:LOGIN_STATUS;
}

root_type LoginRequest;

This generates function called VerifyLoginRequestBuffer however there is no function called VerifyLoginResponseBuffer so I do not now how to verify LoginResponse.

My question is:

How in C++ I can verify table which is not marked as root_type? Can anyone write an example as answer if it is even possible?

P.S. I tried creating some unique function which can check all possible types like so:

template<typename T>
bool VerifyBuffer(flatbuffers::Verifier &verifier){
    verifier.VerifyBuffer<T>(nullptr);
}

So my plan was to provide LoginResponse like so:

bool check = VerifyBuffer<Vibranium::LoginResponse>(&verifier);

However LoginResponse inherits from private flatbuffers::Table which is a problem. So I am stuck inhere.

Functions like VerifyLoginRequestBuffer are "convenience" functions generated for the rout type. You can look at their (small) implementation, and call the exact same function for any other table type.
