Pairing Apple TV Remote App without remote

The dog ate my apple TV remote (let's just accept that premise...)

Now, I cannot pair my iphone 8+ with my Apple TV (2nd generation) while trying to use the Apple TV remote app. I have followed the instructions for "Use the Apple TV Remote app" here.

Specifically, I have downloaded the Apple TV app, and I have tried to pair it with my Apple TV (Steps 1-3). At that point, I receive a 4-digit code on my iPhone, and it says to enter it "ON MY APPLE TV!" It says "to do so, go to Settings>General>Remotes."

What?!

Where am I to enter this? I can't get into the Settings section of my Apple TV because I don't have a remote to do so. I looked in my Settings menu on my iPhone (just in case), but there is nowhere to do it there, either.

Help!

Thanks,
