This is a forked version of the standard CB Applet. Please refer to the README on the main branch of the CloudBoltSoftware/cb-applet repo.
This applet has inbound web hook (iwh) dependencies listed as an array under met_inbound_web_hook_dependencies in the package.json. The corresponding zip files should be placed in xui/additional_files. Unzipped copies of the files are present in xui/additional_files_unzipped to show the code and track changes, but the zipped versions will be what the applet uses.
