I can't connect amazon prime to my tv

[Comps83]

Can anyone help?
I don't know if I'm just being stupid here
LG tv gives me a code to put ... somewhere
Ive downloaded the amazon tv app on my iPhone but can't see where I'm meant to put this code

Are you in the Amazon Prime Video app on your tv?

Yeah so I've opened the app on the tv which tells me to sign in on phone or computer and put the code in
But I can't see where I put the code in?

Done! Sorry!
I was being stupid
Bloody technology

There should be a box where you enter the code. Can you post a pic of the tv screen?

Haha! Good job and problem solved!
