Here is what you need to do:

Enrich, refine, curate a list you made with LinkedIn SalesNavigator.

You can extract up to 2,500 leads.

Don't go over of this limit to limit the risk of being banned by LinkedIn.

You just need to copy paste the search url in here.

And copy paste your session cookie. (this is how the scraper can identify you)

To get the session cookie. Find Li_at and use this chrome extension: https://www.editthiscookie.com/

⚠️ I am working on a chrome extension to get you this automatically, hassle-free.

For the time being, you still need to collect this by yourself. It does take 5 seconds though.
