        timeout: An integer. Set for sniffing with tshark. Default to 50 seconds in this setup.
        interface: A string. Name of the interface to sniff on.
        bpf_filter: A string. The capture filter in bpf syntax 'tcp port 80'. Needs to be changed
                    to match filter for the traffic sent. Not to be confused with the display
                    filters (e.g. tcp.port == 80). The former are much more limited and is used to
                    restrict the size of a raw packet capture, whereas the latter is used to hide
                    some packets from the packet list. More info can be found at
                    https://wiki.wireshark.org/CaptureFilters.
        display_filter: A string. Default to 'tcp.port == 80' (assuming this is the port of the
                        'WebsocketClientWorker'). Please see notes for 'bpf_filter' for details
                        regarding differences. More info can be found at
                        https://wiki.wireshark.org/DisplayFilters.
        tshark_path: Path to the tshark binary. E.g. '/usr/local/bin/tshark'.
        output_file: A string. Path including the output file name is to saved.
                     E.g. '/tmp/mycapture.cap'

        Returns:
        catpure: A 'pyshark.capture.live_capture.LiveCapture' object. Of packets sent
                 over WebSockets.
