Google Analytics 4

Morning!

Has anyone got experience of Google Analytics 4?

I'm about to do a few marketing campaigns and I need to see where the website referrals are coming from. It's been a couple of years since I looked into google analytics and it seems a bit stripped down ahead of its end date next year.

I can view referrals as a number against organic and direct traffic etc but not the actual referral name which is what I need. Back in the day I could click on that number and see the list of sites but it doesn't seem to be there.

Google Analytics 4 seems to be more in depth and the answer but for the life of me I can't find anywhere to download it. A google search just brings up set up and no download.

If anyone can help or recommend another (preferably free) option to view traffic acquisition it would be much appreciated!
