Another trick is to follow up a meeting with the minutes of what was said. It is common in meetings for people to disagree and for no clear decision to come out (particularly on a noisy conference call with 20 participants - I am shocked how poor is the audio quality in 2020, doesn't sound like a hard problem to solve). But whoever controls the minutes controls the narrative and the official outcome of the meeting. To the point where for contentious meetings you can have conflicts on who will take care of the minutes.
