Setting up a Profile allows team members to identify you, which proves particularly helpful in larger organizations or cross-functional teams.
To edit your Profile, click your Profile Icon in the top right corner displaying your initials and select Profile & Account Settings. Next, add your profile picture by hovering over the icon with your initials and selecting Upload a Photo. Complete your remaining profile information (optional).
NOTE: Your photo should be at least 256px by 256px and no more than 100MB in size.
