Hi,

I am trying to create an employee Covid tracker,where

  1. managers will be able to see their direct reportees once they login to the glide app.
  2. Once they login,they can select one of their direct reportee who has been infected with Covid 19 and fill the details in the form(named as Covid Form).
    3.The access for the details of the form will be only visible to the manager.

I have created the similar flow in the glide app,however I am unable to provide the login specific access to managers.

Following is the app link : Glide

Need help.

Thanks
