I got recompile working (in terms of requests, see dmadisetti@d3f621b

BUT, this does not refresh the PDF in browser. I cannot find a hook that will allow us to remotely refresh the browser either. There is a compile response, but this change just ignores it.
The best way I have found to get changes to show in overleaf is just to turn on autocompile, which doesn't need an additional compile request.
