Oculus/Meta Quest Setup Help

I recently got a Oculus Quest 1 from a friend, but he didn't reset it, so I did. However, now I am stuck since it wants me to enter a 5-digit pairing code into to the "Oculus App". Oculus App doesn't exist anymore and the (now) Meta Horizon doesn't have a way to insert that code. I also have the Meta Link, which recognizes the OQ1, but there is nothing I can do from this side and the OQ1 refuses to do anything else before I can enter that 5-digit code. No "maybe later" or "X" to skip.

Is there a way to go around this issue? I would be very happy if someone can help me out with that :C
