Hotjar _hjClosedSurveyInvites Hotjar cookie that is set once a user interacts with an External Link Survey invitation modal. It is used to ensure that the same invite does not reappear if it has already been shown. 365 days
  _hjDonePolls Hotjar cookie that is set once a user completes a survey using the On-site Survey widget. It is used to ensure that the same survey does not reappear if it has already been filled in. 365 days

  _hjid Hotjar cookie that is set when the customer first lands on a page with the Hotjar script. It is used to persist the Hotjar User ID, unique to that site on the browser. This ensures that behavior in subsequent visits to the same site will be attributed to the same user ID. 365 days
  _hjRecordingLastActivity This should be found in Session storage (as opposed to cookies). This gets updated when a user recording starts and when data is sent through the WebSocket (the user performs an action that Hotjar records). Session
  _hjTLDTest When the Hotjar script executes we try to determine the most generic cookie path we should use, instead of the page hostname. This is done so that cookies can be shared across subdomains (where applicable). To determine this, we try to store the _hjTLDTest cookie for different URL substring alternatives until it fails. After this check, the cookie is removed. Session
  _hjUserAttributesHash User Attributes sent through the Hotjar Identify API are cached for the duration of the session in order to know when an attribute has changed and needs to be updated. Session

  _hjViewportId This stores information about the user viewport such as size and dimensions. Session
  _hjRecordingEnabled This is added when a Recording starts and is read when the recording module is initialized to see if the user is already in a recording in a particular session. Session
