Did Biden and Harris hug each other during the convention last night?

A conservative neighbor posted on FB a photo of Biden and Harris hugging during what appeared to be the DNC. There were lots of people right behind them. The post from the neighbor read “Why are we being forced to wear masks if they’re not?”

I am not commenting but I am curious if Biden and Harris actually hugged, and right next to a bunch of convention goers (audience). Nobody had masks on.
