Find a way to set camera aspect ratio as in native camera

Hello,
I’m actualy using @capacitor/camera and @capacitor-community/camera-preview on my app to take pictures.
By default, the app is using 16:9 as aspect ratio and I would like to know it it is possible to change it to 4:3 or something else.
I’m detecting that I’m missing some information on the bottom and the top of the image when I use 16:9 as aspect ratio.
Thank you in advance
