Name od movie about a cult family

Around 2018, I watched a movie on my TV (possibly HBO but I’m not sure).

It was about this weird and a bit creepy family that was looking for a babysitter. A girl reached out and they offered a big pay for it so she accepted.
Turned out the family a part of cult and their plan was to make her a part of it, but slowly.
I think the girl manages to escape and call the cops on them. But in the end it was revealed that the cult is all over the world.

That’s all I remember. I searched everywhere but couldn’t find it. I would really appreciate if someone could tell me the name of the movie if they know it.

Sounds a little bit similar to House of the Devil?
