Springing People from the Poverty Trap

I'm curious how this relates to givedirectly's research https://www.givedirectly.org/research-at-give-directly/

As far as I know givedirectly have found that cash transfers are effective at improving people's long term wealth. But I've never heard anything about them moving people from the poor to the "less poor" mode of a bimodal wealth distribution. Maybe the difference is that this experiment was run in a place that has a clear bimodal distribution, which allowed them to observe this more easily?

Wish I could read the paper but it's behind a paywall and not on scihub.
