There are two ways you can add new friends.
Method 1: Add via Friends Icon
Click on the icon with two people in the top right corner next to your profile picture.
In the "Find Friends" search field, you can search for both existing friends and new ones you wish to add.
Method 2: Sharing Profiles
Your friends can also share their profiles with you. They can do this via a link, SMS, QR code, or any other method. To share their profile, they need to go to their own profile, click the paper airplane icon in the top right corner, and choose a sharing method.
When you receive a link to a profile, you will be directed straight to their page, where you can easily add them as a friend by clicking the "Add Friend" button.
You can find your friend requests under the icon with two people in the "Requests" section, where you can accept or decline the requests.
