"Knox Deployment" : what does this screen want me to do, exactly?

I recently purchased a Samsung A23 and today I "factory reset" it. The first screen that appears during first boot (after "factory reset") says the following: > Knox Deployment > > Samsung's Knox Enrolment Service enables you to enrol your phone with > a company. Select an option below to start enrolment. > > Bluetooth: Enrol by pairing your phone with your IT admin's device. By > proceeding, you agree to allow access to your phone's location. > > Wi-Fi Direct: Enrol through a Wi-Fi Direct connection to your IT > admin's device. By proceeding, you agree to allow access to your > phone's location. > > QR code: Enrol by scanning a QR code. By proceeding, you agree to > allow access to the camera. I have never enrolled with Knox before, and I can do nothing with my IT admin's device because I have no IT admin. I am confused by the wording used on this screen. Does this screen mean that my phone has ***previously*** been enrolled with Knox i.e. that I need to know the credentials of the previous enrolment for me to be able to continue to use the phone? Or is this screen trying to get me to enrol my phone with Knox ***for the first time***? TIA.
