With the update, users need not hang up and manually add people into a conversation before restarting the call.
"We're excited to share a small new feature that will hopefully have a big impact to make your video and audio chats easier and faster than ever," Sarah Morris, Product Manager of Messenger, wrote in a blog post on Wednesday.
Earlier, to turn a one-on-one video or audio chat into a group chat, users had to hang up, start a new conversation from your inbox -- either by creating an entirely new message or by searching for an old one -- and then turn that conversation into a call.
While in a video chat or on a voice call, tap the screen, select the "add person" icon and choose who you want to join.
