Due to 'COVID' related sick leave and lack of staffing; a south satellite CIC was not utilized during one of the three daily rushes into ZZZ.  I was assigned Flight Data; but observed a problem developing with ZZZ1 Approach who handles half the feed into ZZZ.  The CIC was combined to the AF position which was being staffed by a Supervisor.  The Supervisor was involved with a conversation related to staffing and break rotation with other supervisors and not actively monitoring the south satellite line.  I was assigned Flight Data; however I sat down at the X position and started acting as a CIC despite not being assigned the position.  X is a supervisory position and I was acting in a supervisory capacity without being delegated the duties.  I am certified on the position.  I could not just sit by and watch management not supervise and act according just let the controllers flounder.  I ended up slowing the fix and doing all of sector Y's coordination. While he worked the traffic.A CIC needs to be sat down any time there is a rush.  At a minimum management needs to pay at least some attention to a line they are in charge of during a rush.
TRACON Controller reported assuming a position to act as CIC because in reporter's mind the Supervisor CIC was not properly monitoring.
