User Name not available in stepContext.Context.Activity.From.Name when using MS Botframework V4 (c#) over WebChat using Directline channel

Question

Problem Statement

Am using MS Botframework V4 (c#) using Directline channel over MS Web Chat. Have successfully integrated with Azure Active directory and am successfully able to authenticate/ login using an Azure AD account from the MS Web Chat widget.

Unfortunately the Logged in User Name is not available in stepContext.Context.Activity.From.Name property.

Other Details

following are the values of other properties when debugged using MS Bot framework Emulator:
stepContext.Context.Activity.ChannelId : "emulator"
stepContext.Context.Activity.CallerId : "urn:botframework:azure"
stepContext.Context.Activity.From.Name : "User"
stepContext.Context.Activity.From.Role : "User"
stepContext.Context.Activity.TextFormat : "plain"
stepContext.Context.Activity.Recipient.Name : "Bot"
