Where Are The Constants Defined

I’ve found some code for the JitsiConference.startRecording here:

let recordingConfig;

            if (mode === JitsiRecordingConstants.mode.FILE) {
                if (dropboxToken) {
                    recordingConfig = {
                        mode: JitsiRecordingConstants.mode.FILE,
                        appData: JSON.stringify({
                            'file_recording_metadata': {
                                'upload_credentials': {
                                    'service_name': RECORDING_TYPES.DROPBOX,
                                    'token': dropboxToken
                                }
                            }
                        })
                    };
                } else {
                    recordingConfig = {
                        mode: JitsiRecordingConstants.mode.FILE,
                        appData: JSON.stringify({
                            'file_recording_metadata': {
                                'share': shouldShare
                            }
                        })
                    };
                }
            } else if (mode === JitsiRecordingConstants.mode.STREAM) {
                recordingConfig = {
                    broadcastId: youtubeBroadcastID,
                    mode: JitsiRecordingConstants.mode.STREAM,
                    streamId: youtubeStreamKey
                };
            } else {
                logger.error('Invalid recording mode provided');

                return;
            }

            conference.startRecording(recordingConfig);

I am having trouble finding the constants JitsiRecordingConstants.mode.STREAM . For example:

The mode.STREAM and mode.FILE is missing. Does anyone know where I can find a complete list of constants that can be used?

Not sure about that fork which seems pretty old, but I did a quick search in master and found the following in lib-jitsi-meet:

Which I believe indirectly references:
