no input field in gui for "custom bat file"

[wspatgithub]

as described in the parameters there should be a field to fill in a path to a bat file. On the gui I did not find that field. If I put in the example "C:\Users\HaveAGitGat\Desktop\Input\CopyToBackupDrive.bat" in the configuration file, the start failed. Please advise Thanks

P.S. I am working on macOS
