Workout after comminuted humerus fractur

I'm 31 years old Male diagnosed with supracondylar fracture elbow with comminuted Intracondylar extension right humerus. Surgery underwent is ORIF with Locking Recon plating under general anaesthesia. This happened 5 years 7 months ago. There are 2 plates and 9 screws in my right arm. Recently, 6 months ago I visited the same Dr and thankfully he said union is complete and implants can be removed. But due to this pandemic I couldn’t able to go for surgery. Now I recently started doing some light workouts at home like push ups every day and I’m not feeling any pain or discomfort. My question is whether I can start doing workouts in gym like weight lifting? Can I do it safely without causing any issues or damage to my bone? If I can do it, should I be taking any specific precautions? Also if I get any pain should I stop immediately? I’ve attached 2 X-Rays. One is taken on day of accident (Feb-2015) and another is latest one with implants (Mar-2020). Thank you in advance for your response
