Integrate ASP.NET Core Identity with JWT and minimal APIs

In the previous part of this multipart article series we implemented JWT authentication in CRUD minimal APIs. Recollect that we are using a hard-coded user name and password while issuing the token in the getToken handler function. Wouldn't it be nice if we integrate ASP.NET Core Identity into app so that membership features such as account creation and user validations are taken care of easily? That's the agenda for this part of the article.
