Kissinger dodders over to block the purse from Kelly’s view. He’s running interference...
Here is a good snippet with just the incident from the embrace through LG whispering in JK’s ear:

General Kelly touches his face at 21 seconds in, followed by Lindsey Graham reaching down to his pocket, checking if the flap was down, then reaching down to the bottom of his pocket and feeling something distinguishable inside.
I think this was possibly a drop by Huma to LG ... there may have been reciprocal of LG dropping something in Huma’s purse. But something (one or both) happened here IMO.
