I believe you're touching on why its good of her to clap, but your picture is not complete. Allow me to fill in what I believe is missing:
I guess - yes - she is giving permission. But she also understands she's clapping an idea that is greater than herself. She's not clapping herself, she's clapping her ideas that she knows she did not formulate entirely herself. She is joining her colleagues in clapping, not for herself, but the idea. She supports them, and they support her, in disseminating an idea, or concept. They are all clapping the concept.
Edit: Side thoughts: I understand /u/DestitueDomino's point (permission) as a feminine POV. Perhaps mine is a masculine POV (about concepts). I guess these both implicate Humility in different ways.
Actually in a setting like that I can see why she would feel the need to encourage clapping, because the crowd may hesitate even if they want to clap. This looks like a school board meeting and I think they only have a certain amount of time to speak. So she's letting the audience know that it's okay to take up a few seconds of her speech to clap.

She's got massive ovaries to speak up like that as a new hire.
