To get this token we call [AcquireTokenSilent]([https://docs.microsoft.com/en-us/dotnet/api/microsoft.identity.client.clientapplicationbase.acquiretokensilent?view=azure-dotnet](https://docs.microsoft.com/en-us/dotnet/api/microsoft.identity.client.clientapplicationbase.acquiretokensilent?view=azure-dotnet)) method, which attempts to acquire it from the user token cache first avoiding extra call to the Identity Provider.
