ASP.NET Core 7 Blazor theme identity

I added the identity to the ASP.NET Core 7 Blazor app. But for the Identity pages, how do you use the out-of-the-box Blazor theme?

I want it to be the same style as the "Hello world!" page, but it is generated in the standard theme.

How can I configure the ASP.NET Core 7 identity to use the Blazor out-of-the-box Blazor theme?
