Angular/Laravel video game database. Help with function

I'm working on a database for video games which i need to add a function to. The function shall save the selected video game on to the users profile in a "my favorites" list. The stack is angular/laravel. I'm currently fetching from the API and displaying them on the front page. User authentication works and the game needs to be saved to a seperate list on the profile with an own route to click to get to the game.
