Launch an Rproj from Shiny

I want to wire an actionButton in each row of a data table that launches an Rproj file in a new session. I tried onclick = window.open("path_to_project.Rproj") to no avail.

Can I access the {rstudioapi} package within Shiny? Basically, I want onclick = rstudioapi::openProject(), but translated to JavaScript.

Another option is to program an observer for each row/project in the server?
