Uninstall App that appears after a call

[AC Question]

I bought my Samsung Galaxy a5 2016 just 2 days ago. I must have installed something by mistake and I can't uninstall it as I don't know which app to remove. Each time I finish a call, I get a new screen that I can choose if I want to call or text the number I was just calling. I have a screenshot if it would be helpful. Although I don't know how to attach it here.... Please help me!!!!

That comes up after a call, part of Samsung's add-ons I guess.
