If there is a talking point that you don't want to disclose, you can easily mark them as hidden to hide them from the other party.
All you need to do is click the "Hide" button while adding your talking points.
Since Teamflect syncs talking points in near real-time, if you add a talking point and then click the "Hide" button, that talking point can become visible for a very short period.
However, if you mark the talking point as hidden while arranging the 1-on-1 meeting using Teamflect, it will not appear to the other party at all and the hidden talking point will not be added to the meeting invite like the other regular talking points.
