How to edit a scan?

We are trying to edit an existing scheduled scan so we can get an email notification once the scan is complete however we are unable to find the option to edit the same. Could you please let us know if it is possible to do so?

The Edit Schedule only allows to change the scheduling options, not the
scan details. If the schedule has been created through a template, adding
an email notification can be done with:
- Open Scan Templates in the menu
- Click on the template name
- Click Edit
- Change the options you like and save changes
