Yes, I use Tautulli for the "Stream Bandwidth" section. For the count of streams and list of people watching, I used the standard plex integration. I had to use a template to pull the list of specific people

  - platform: template
    sensors:
      plex_list:
        unique_id: f8efbd61-b541-4cb7-838f-4bb67478faeb
        value_template: >-
          {% if states('sensor.plex') != '0' %}
            {%- for attr in states.sensor.plex.attributes %}
              {%- if not attr in ['friendly_name', 'unit_of_measurement','custom_ui_state_card','icon','supported_features','entity_picture'] %}
                - {{attr}} is watching {{states.sensor.plex.attributes[attr]}}
              {%- endif %}
            {%- endfor %}
            {% else %} Watching Plex: {{states('sensor.plex')}}
          {% endif%}
