On my Tab S6 with Android 12 it looks like this:
Settings > Battery and device maintenance > Storage > Apps
All apps and their storage requirements are listed here. With a touch on the respective app and then touch on memory, you can see how much memory the app needs and how much memory the data in the app needs. As an example for the Navi app, I see 300 MB for the app and 930 MB for the data. This shows me that it is not the app itself but the offline maps that are the big memory hogs.
