Go to 1-on-1 meeting page and open the 1-on-1 of which you want to view the notes. Your shared and private notes will be stored in our 1-on-1 meeting page.
Your Shared Notes consist of your and the attendees talking points and action items and both the attendees can view these notes.
The Private Notes section is right below Shared Notes. These notes are only visible to you. The other meeting attendee can't view your private notes.
Alternatively, to search quicker, you can use the ‘Ctrl+F or Cmd+F’ (search shortcut) to find the 1-on-1 using relevant keyword. Once you find the 1-on-1 meeting, you can access your shared and private notes inside it.
