You may also use the Azure Key vault to store all your ngSurvey configuration settings including the connectionstring instead of using the web.config file.
To configure your keyvault set following environment variables with your keyvault settings.
KeyVault:Name is the name of your azure key vault
AzureAd:ClientId is the client id to access your key vault
AzureAd:ClientSecret is the client secret to access your key vault
