Instagram wants you to feel comfortable as you video-call your friends during the coronavirus quarantine, so it’s introducing a feature that lets you check out posts together.

Co-watching, as the company calls it, essentially makes it possible to pull up any post directly in group video chats. Once in a conference call, all you need to do is click the Posts icon at the bottom of your screen, and select the post you want to share. It’ll then show up for everyone else in the video chat.
