How to enable changePassword notification in Blazor?

I have searched through radzen-examples-master and was unable to find a way to code the change password dialog's submit event such that it sends notifications upon success, failure or inconsistent confirm password. Currently, there are no notifications, and there are no warnings even if I anyhow enter the 3 textboxes. It appears that the angular version works, but I have no idea how to get the blazor version working. Can you please share a working blazor example?

Changing password in Blazor is performed with form submit and that is why notifications are not possible. In Angular the same is performed with a service call however this is not possible in Blazor.
