How to adjust the camera for different screen ratios?

Question

Unity

Hello, I would like to know how to make it so that when the screen ratio changes (for example, from 16:9 to 4:3), instead of narrowing the sides, the height increases. Or initially set the camera to a scale that would fit all resolutions?

Alternatively, you can manually write the code, as here: https://www.cyberforum.ru/unity/thread1398203.html
