As a user
I want to see my username on the UI to verify
So that I can be sure about the user who is currently logged in and this avoids confusion during testing especially

Acceptance criteria:

• Logout title to display the user name in the next line

• Font size to be kept one or two size smaller than the Logout title

• Font color to be kept in Grey (Secondary color) so that the name is differentiated

• Approx character limit is 20 that should be visible on the UI
