I saw an ESRI - produced dashboard that did something like this during COVID - everyone would check in and I believe the dashboard kept track of the number of people in the office, the number of remote workers etc. It could be modified, I expect. It was called the Coronavirus Business Continuity app and it worked well. Maybe you could edit it to take out the virus part and just use the check in form and map/dashboard part. Hope this is helpful and sorry I can't remember more...
