I'm trying to use some commands from the rstudioapi package but don't know how to pass arguments to these commands. The goal is to be able to export a file from RStudio Server

and I know this can be done with rstudioapi::executeCommand('exportFiles'), but I need to be able to select the files first. I think I want rstudioapi::executeCommand('findSelectAll')but I dont know how to send arguments of what to find and select.
If there is documentation for these commands I would appreciate those links as well. I've looked at the RStudio Server documentation and these are only mentioned in the Appendix by name, but no other information.
