Modal Window
The Window for Blazor can be modal so that the user is unable to interact with the rest of the page until it closes.
To make a modal window, set its Modal property to true.
It is possible for users to close a modal Window by clicking on the modal background around it. To allow this behavior, set CloseOnOverlayClick to true.
