I try to use SPA Identity in .NET 8 – https://learn.microsoft.com/en-us/aspnet/core/security/authentication/identity-api-authorization?view=aspnetcore-8.0#test-registration

it’s works fine, but I need two things:

1. change e-mail texts – framework sending some standart text, but i need send my own html template
2. after registration I need start some backgroud proccess

I am not able to find how to do that… any advice or example?

Thank you
