How do I activate/redeem this rebirth code?

I found a very nice woman that was selling those REBIRTH codes for just a couple thousand euro, so I got one for me and all my family.

The problem is that I see no way to apply/redeem those codes? Where to type? The instructions say to align my soul with the northern lights but that's not clear. Am I supposed to get a confirmation message when redeemed?

I tried to contact the seller but she's not answering my calls

Edit: I forgot to censor the code but I don't know how to replace the image in this post. DO NOT REDEEM!
