What is the minimum internet speed required for WFH tasks?

I’m working remotely in a different state from where my employer is located. What’s the best internet speed for running AutoCAD Civil3D 2020 remotely via the company’s VPN. In the office, the current speeds right now are: Download – 413 Mbps/ Upload – 778Mbps. I’m sure I don’t need that much since I’ll be the only one on the line. I have been using my connection to earn extra cash here and it works great, but I am not sure if the same applies for a regular job.
