Need help with Google Play Games | External Login UI not working

I’m developing a video game, it’s already published on google playstore, I already have the googleplay services configuration and I’m trying to integrate leaderboards and achievements but I can’t get it to work I’ve followed the examples of these url’s but it still doesn’t work, I don’t know what I’m doing wrong or if there’s something else that I am not contemplating.
I am using unreal engine 4.25
