Navigate to the More tab within the mobile navigation.
In the upper right corner of the app, click on the Edit button.
You can now edit any profile field.
Click on the profile field you wish to edit.
If it's a text form-based field, you can enter your own text (for example: projects, hobbies).
If there is a pre-defined selection available, you can choose from available options (for example: languages, software skills).
If it's a user selection field, a new window will open. Enter the name of the user and select them to save them, for example as your superior.
When you are done, click on the Save button in the upper right corner.
