Ran into this today - noticed that if I have a NTP open when enabling one of the widgets from brave://settings, then the widget displays on the NTP. However, as with @srirambv steps if I don't have a NTP open when enabling widget from brave://settings, then the widget does not get displayed.

Reproduces for Binance widget as well as Rewards widget.
