Orca not working

Hello,

I love this package (great job).

The only problem I am having is exporting 3D scatterplots as png screenshots.

Error in rethrow_call(c_processx_exec, command, c(command, args), pty, :
Command 'orca' not found @win/processx.c:982 (processx_exec)
Type .Last.error.trace to see where the error occurred

I am trying to use orca but I am receiving errors. I have done a lot of scrolling around online and found that I am not the only one experiencing these issues. There are a number of posts from the orca package (please see below) which attribute this to plotly package rather than orca.

In the interim I have also tried using the plotly::export function although I am getting the error below. It asks me to check the examples in help (i.e. help(export)), but the documentation explains the selenium argument without any examples. I have tried to stay away from plotly::export as it is in the process of being deprecated.

Error: Must provide an object of class 'rsClientServer' to the selenium argument to export this plot (see examples section on help(export))
In addition: Warning message:
Error: Must provide an object of class 'rsClientServer' to the selenium argument to export this plot (see examples section on help(export))

No source file or test is identified. Begin by reproducing the Windows orca-not-found error and reading plotly::export and help(export) around the selenium argument. Done would require determining and documenting a supported path for exporting the reported 3D scatterplot as a PNG.
