In this code snippet
authority, validateAuthority, executor (authenticationContext )? - How should i fill these values? what do they means ?
powerBiResourceId? - Where is this id , what does it means?
nativeClientId - I'm making a web app (not native app) and this will be ApplicationId in Azure?
username + "@" + tenant - I know this
password - I know this
