How to change the commandLink programmatically?

Question

Hi, I am working on creating the custom credential Provider

Flow:

1. User attempting to login
2. Username, and password check
3. Auth result

I want to make a 2nd chance for user if their password is not correct by letting the user input the password by themselves directly.
So the flow will be:

1. User attempting to login
2. Username, and password check
   3. Incorrect password
3. Using the same username and domain, please input the correct password
4. Auth result

The "Sign in" text is build based on CPFT_COMMAND_LINK which I disabled (so the used cannot clicked it)

Since it is a 2nd attempt, I just show the password field right after the failed attempt detected

HRESULT CMyCredential::ReportResult(  
 NTSTATUS ntsStatus,  
 NTSTATUS ntsSubstatus,  
 PWSTR* ppwszOptionalStatusText,  
 CREDENTIAL_PROVIDER_STATUS_ICON* pcpsiOptionalStatusIcon  
)  
{  
if (!SUCCEEDED(HRESULT_FROM_NT(ntsStatus)))  
 {  
 if (_pCredProvCredentialEvents)  
 {  
 IsWrongPassword = true;  
 LOG_DEBUG << "Wrong password???";  
  
 //password --> show  
 _pCredProvCredentialEvents->SetFieldState(this, s_rgCredProvFieldDescriptors[SFI_PASSWORD].dwFieldID, CPFS_DISPLAY_IN_BOTH);  
 _pCredProvCredentialEvents->SetFieldInteractiveState(this, s_rgCredProvFieldDescriptors[SFI_PASSWORD].dwFieldID, CPFIS_NONE);  
  
 //Change the "sign-in to" value  
                    string tempInfo = "Sign in to: " + _savedUser._username;  
 HRESULT hr;  
 hr = SHStrDupW((LPCWSTR)tempInfo.c_str(), &_rgFieldStrings[SFI_SIGN_IN_TO_TEXT]);  // --> naively, I think this is how it should be done ._.  
  
 _pCredProvCredentialEvents->SetFieldState(this, s_rgCredProvFieldDescriptors[SFI_SIGN_IN_TO_TEXT].dwFieldID, CPFS_DISPLAY_IN_BOTH);  
 _pCredProvCredentialEvents->SetFieldInteractiveState(this, s_rgCredProvFieldDescriptors[SFI_SIGN_IN_TO_TEXT].dwFieldID, CPFIS_NONE);  
 }  
 }  
}

Question---------------
Well the password field is shown but the commandlink text is still the same with the one that I instantiated at the beginning

Is my Approach correct by using SHStrDupW?

I just take the inspiration from the instantiation like this:

HRESULT CMyCredential::Initialize(  
 CREDENTIAL_PROVIDER_USAGE_SCENARIO cpus,  
 const CREDENTIAL_PROVIDER_FIELD_DESCRIPTOR* rgcpfd,  
 const FIELD_STATE_PAIR* rgfsp,  
){  
   ...  
HRESULT hr = S_OK;  
  
if (SUCCEEDED(hr))  
 {  
 hr = SHStrDupW(L"Sign into: ", &_rgFieldStrings[SFI_SIGN_IN_TO_TEXT]);  
 }  
  
   ...  
}
