Flash Card Component

I used the tutorial of “Josh Morony” to create a quiz about Ionic. In his home.ts he uses the setTimeout (), but I would like to replace it with a button, it’s been several hours that I try different combination without ever finding the solution. If anyone could help me, it would be great.

  selectAnswer(answer, question){
        this.hasAnswered = true;
        answer.selected = true;
        question.flashCardFlipped = true;
        setTimeout(() => {
                this.hasAnswered = false;
                answer.selected = false;
                question.flashCardFlipped = false;
                }, 3000)


I am available if you have questions, Thank You
