"subType" doesn't exist in credential_data

Getting advice
1

In a Keycloak 24 custom extension I add the next code to create ned OTP credential:

        UserCredentialModel credentials = new UserCredentialModel();
        credentials.setType(CredentialModel.OTP);
        credentials.setValue(secondFactorSecret);
        user.credentialManager().updateCredential(credentials);

Now, I cannot see “subType: totp” in the database , field “credential.credential_data”

I solved the problem by creating a new credential provider.
