A Fractional Jet First Officer reported a Wing Overheat warning on initial approach to their destination.

Narrative

ZZZ1 to ZZZ; part 135; one passenger. I was the PF; in the left seat; in clear weather. While flying the ZZZZZ arrival; approaching ZZZZZ1 about 10 miles north of ZZZ at 4000 ft and 210 kts; we got a A/I WING O'TEMP L amber CAS (Crew Alerting System) message. I kept flying and took over the radios. The PIC was the PM in the right seat and immediately referenced the QRH. About 30 seconds later the CAS message changed to a red A/I WING O'TEMP L. He referenced the appropriate QRH pages and accomplished the checklist to completion. Next; the PM referenced the Anti-Ice page and noted the left wing temperature was approximately 293 C and climbing. It continued to climb to approx 306 C while on dogleg to final. We decided we were not going to taxi to the FBO and would shutdown on a taxiway once clear of the runway. Approaching the final approach fix the PM took over the radios and advised ZZZ tower we were [requesting priority handling] and our intentions.We landed uneventfully on runway XXL; turned left on taxiway 1; entered the parallel taxiway 2; stopped; and shut down. I stayed in the cockpit and advised ground we were ok. They said the fire department was monitoring the frequency. No one approached the aircraft; I noted the left wing temperature was still approx 306 C; shut off the batteries after 3 minutes; and advised the PIC to open the cabin door. The PIC was already out of his seat; explaining to the passenger of what had happened; and opened the door. Here's where it got a bit confusing. The PIC requested I call ZZZ [operations] and have the passenger be taken care of and a tow crew come get us. The fire department ended up giving the passenger a ride to the FBO and an FBO tow crew showed up. We told them thanks and waited for another FBO tow crew to pull us back to the company facility.
