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))

ソースファイルもテストも特定されていません。まず、orca が見つからないという Windows のエラーを再現し、selenium 引数に関する plotly::export と help(export) を読みます。完了とみなすには、報告された 3D 散布図を PNG としてエクスポートするための、サポートされている方法を特定して文書化する必要があります。
