This one needs environment variables set before it will start: ARDUINO_CLI_PATH (Optional path to arduino-cli binary. Defaults to arduino-cli on PATH.), ARDUINO_SKETCH_ROOT (Optional absolute path restricting sketch operations to this directory.). The author declared them in the registry entry; get the values from the project itself.
