You can add a team member with the "Link-level permissions" option, that allows the team member to see only short links that he/she has created. With the "Link Permissions" feature, other team members can give users with the "Link-level permissions" access to individual short links.
Note: The feature is available starting from the Team plan.
How to give permission to a link:
1. Go to your Short.io account.
2. Click the Edit icon near a short link to which you want to open access.
3. Open the "Link Permissions" tab.
4. Choose a user to give access to > Click Grant access.
Now the team member sees his/her self-created links and the link to which was given permission.
