You have to join the discord channel to qualify then do the gleam linking to verify to be provided with the early access key you can redeem via EA's app(whatever Origin is now). iirc preload is ~40GB.
There will also be activations via twitch(watching peoples stream for ~30min or something) and the open beta on the weekend I think.

Open the https://gleam.io/sYN9X/razer-battlefield-6-open-beta-early-a… page (leave it open)
Click the "?", this will open discord and have you join the razer discord server
Back on the gleam page, click "Continue"
Accept the authorization for Gleam to access your discord info (same as authenticating an app)
Go back to the gleam page (remember, never close it!) and the key should now appear (You will also get the key sent to you in the email that's attached to your discord account)
Redeem the key on ea.com or in the launcher, etc. ( https://www.ea.com/games/battlefield/battlefield-6/redeem )
After redeeming the key you can go back and remove the gleam.io app from your discord if you want. Discord -> settings -> "Authorized Apps" -> find Gleam.io and click "Deauthorize"
I've marked as expired for now, they announced 50k keys to give away and gave away 110k according to their discord and are out of early access keys. Happened within 2 mins of posting :(.
