After reading through your link this wouldn’t be aggravated assault. Doesn’t meet any of the requirements listed.

https://codes.findlaw.com/ga/title-16-crimes-and-offenses/ga-code-sect-16-5-21.html

(1) With intent to murder, to rape, or to rob;

(2) With a deadly weapon or with any object, device, or instrument which, when used offensively against a person, is likely to or actually does result in serious bodily injury;

(3) With any object, device, or instrument which, when used offensively against a person, is likely to or actually does result in strangulation;  or

(4) A person or persons without legal justification by discharging a firearm from within a motor vehicle toward a person or persons.

This will be simple assault and probably false imprisonment. The false imprisonment will be the felony.

Edit. Link of where I got the list. Had and additional entry over the previous linked on.

We don't know the full facts, but you could definitely argue (2)(3)
