Silent Sign in

[SVarasteh]

Hi,
We are utilizing Identity Server 4 for authentication/authorization users in our application which is a spa web app. The client flow is implicit. Now we need to change our registration flow so users were not required to login following registration.
I found this link : https://benfoster.io/blog/identity-server-post-registration-sign-in
it is related to Identity Server 3 and I am not sure if I can customize it for Identity Server 4.
I'd be thankful if you can guide me to choose a secure and suitable approach.

Thanks in advance,
Saeideh
