FAQ accordion using CSS Flexbox and Javascript

Hello community! I am still learning javascript and the basics of it. I had trouble alternating between the plus and minus icons. Once I finally got it to work, you can still see the plus icon behind it. How would you typically switch between icons, making one or the other visible based on clicks?

I also had trouble expanding the paragraph element within javascript. I got it to work when the icons were clicked, then I got it to work when the questions were clicked but then it wouldn't work with the icons anymore. Is there a way to add two variables to the same forEach method? How would I be able to have two different variables perform the same function?

I appreciate any help/criticism!
