How can I get the Edith Downes stranger mission?

I remember seeing a stranger mission from Edith Downes in Annesburg some time ago, but now it's gone. Does anyone know how I can get it again?

I'm currently at Chapter 6.


According to this website

Stranger Missions are side quests that can be found across the Wild West [and] be given by strangers at specific locations. The Strangers may only appear during specific time of the day.

The chapter you're in shouldn't matter since

unlike narrative missions, Stranger's tasks can be started and finished at any time.

The website that quote is from also lists the different Stranger Missions, but I was unable to find the one that Edith Downes should trigger. Cross-referencing with her missions as listed here, she doesn't seem to be involved in any. Are you maybe confused with Do Not Seek Absolution I?
