I want my 2D game to be playable (auto scale) in all screen resolution. I'm using Cinemachine & under "perspective" mode. I found tutorial to change the screen in "orthographic" mode but there is no answer for "perspective" mode using Cinemachine. Please help on what setting must be done in Cinemachine or if there is any scripting that I can use. Thanks a lot.
NB: I tried to add a script as in below link. But it doesn't work. Perhaps it's because I'm using Cinemachine instead of normal main camera. Link: Scale camera to fit screen size unity
Edit: Added picture of the "perfect" view I want below.
Image "expanded" to left & right when I change to "free aspect"
