How to get data from a plotly r-studio graphic

I’m trying to get the data from some graphics created with RStudio [1] I can get the data by hand by copy/paste from the devtools network panel (there is a xhr_streaming call where shiny server sends data to the browser) but I can’t do it programmatically.

Is there a better and easier way to do it that i could set in a cron task daily?
