How to Access Exorcism of the Legion's DLC Epilogue?

As the title suggests. Does anyone know how to do so? Thanks a lot!

I already updated the game and tried to start this new chapter but there was no option to do so. Upon launching the game and entering the precinct, I see the same 5 chapters I already completed on the case board. All of them say "REVISIT" so I am sure I have finished them all previously. The case files also have the "complete this chapter" box checked. Nothing looks different in the precinct and I tried interacting with everything I could but nothing happened.
