If you’re looking to add someone to a group chat on Instagram, there are a few things you need to do. First, open the app and sign in. Then, find the group chat that you want to join and click on the blue “Add Member” button. Next, enter your username and password and click on the “Add Member” button again. Finally, select whether you want to add them as a friend or an acquaintance. Once they’ve been added, they’ll be listed in the “Friends” section of the app and can be accessed from there.
