Calling Microsoft Graph from macOS swift app in load method

I have a requirement where I need to call Graph API after getting token from AzureAD using MSAL and then to continue with other functions in viewDidLoad() method. I have tried, but the issue is, the application fails to get token using acquireTokenSilently and does not call acquireTokenInteractively in between the app form was loaded. Can you please help, I need this on urgent basis.
