Generally speaking terrible advice for anyone in such a situation in a professional group setting.
If you can sense that someone is tense or "off vibe" in a group meeting, you should be able to reasonably determine why. If it's not immediately evident and they are not alluding to it in the meeting - then you should table the discussion until you are able to chat 1:1 with the person.
Not downplaying any of the strategies for being chipper and staying positive and being a good vibe... which seems obvious... but to push it back on the "bad viber" and dice roll on whether you'll be charismatic enough to do it without causing even more bad/awkward vibes, I think is unnecessarily risky.
I've been in many meetings where someone seemed "off" but after conferring with others more familiar with the situation found it it's quite usual and not a sign of anything wrong. Had someone intervened there and tried to "discover" the case of the bad vibes, it would have amounted to "why are you like this" which is not the kind of thermometer input required.
Likewise if someone is being openly confrontational in the meeting because they feel strongly about something, the right course is for someone else to step up and discuss it without any ambiguity or levity - ruling out irrelevant emotions not related to the discussion - if the stakes were high enough to merit losing face in a meeting, they should generally be high enough to discuss and resolve.
My experience has been, in many board meetings and conference rooms with C-levels, that the norm for these discussions is someone "off vibe" and it's rarely koombayah when there is something at stake being discussed. Bringing unnecessary levity to a serious and often uncomfortable meeting is taken as a bit of an insult to the topic or the opinions being tabled. You can read accounts of an Jeff Besoz or Steve Jobs executive meeting and glare into this first hand.
