Narrative:

I was working the local control east and west position combined; south operation; landing runway xxr and runway yyl; departing runway xxr and runway yyr. Aircraft X checked in on final approach to runway xxr and was cleared to land. I continued with the duties required of me at the time when the conflict alert alarmed. I processed the information as quickly as I could (overlapping tags); then immediately began to issue traffic while realizing the conflicting aircraft had passed east of my traffic.keep a sup/controller in charge in the tower not combined with any other position to help scan the movement areas and assist as needed. Although; we are working half the traffic that we are accustomed to; complexity is added due to the combining of positions; runway; and taxiway closures; numerous vehicle calls due to airport construction. Due to the global pandemic we are already working short staffed; so I would not recommend taking a needed body off a crew to accommodate leave on another shift.
