Bypassing Flowable Work App Login Page

I got the Flowable Work app up and running on my local machine, and I am able to login interactively through the built in Admin account.

I got a use case that the login credential is embedded inside the HTTP header and the login page needs to be skipped. With a custom SpringBoot servlet filter that inserted before UsernamePasswordAuthenticationFilter I can create an authentication object successfully and the success login handler is executed as well, but I just end up in an empty page, the Flowable Work main page cannot be shown.

May I know is there any example I can refer to? I just need auto login, no LDAP or SSO integration at all.

Any help is much welcome!
