How to "actually" network for jobs at ML conferences? [D]

Attending ICML for the first time (virtually) next week as a 3rd year PhD student in the US.

I want to get into industry after finishing and have heard a lot about the benefits of networking at conferences to build industry connections. How do you actually go about doing this? Are there gonna be industry reps at the conference who you just go up to and talk to, send LinkedIn connections, and get to know them?

Previously only been to one domain-specific conference and had more students/academic people than industry.

TLDR: What's the best way to network at these big AI/ML conferences, especially since I'm gonna be attending virtually, with the goal of working in industry as a RE/RS in a couple of years?

Would really appreciate any insights or helpful advice. Thanks!

Edit: Only going remotely because I got a free pass (from being a gold reviewer) and cannot travel that far (to Korea) because of expenses :(
