That's your perfect solution right there ^
It does what you wanted.
There are some very good Camera apps like Open Camera that are generally superior or have more features than the stock camera app on a phone.
However they can also be simple or simpler than the original. That's why they are downloaded in the millions.
50 million+ Open Camera downloads :

You can move the app icon to the position your camera app is now, but still retain Samsung"s camera app in the app drawer or a Home screen.
If you just wanted to complain you should write to Samsung, South Korea and ask them to update all A52's over the air so they have your feature but that very few others will use.
Good luck.
Make sure you get the newer A52s 5g with a better Snapdragon 778 chipset and already reduced. I've been fancying it as well. IP68, 120hz Amoled screen, headphone jack, sd card slot, cameras with OIS.....
