Help with Steam Integration

Hello, im new to this forum so sorry if I say something bad.
So, I got a problem with Steam Integration, when I install the applications, it's alright, I setup everything right, Steam API key and all that, but when I need to type in my Steam ID in my profile settings, there is nothing. I just can't find how to link my Steam ID to my profile. My IPS version is: 4.2.7
Thank you.
