Resolve /app in Flatpak's /proc/<pid/maps

Hello, guys. I really need some help here, I have asked this in so many places and have never gotten a response. Basically, on Linux there's the

/proc/<pid>/maps

/proc/<pid>/maps

file which displays the paths of loaded modules. Something like this

50000000-5100000  rwx-   /usr/lib/libc.so

50000000-5100000  rwx-   /usr/lib/libc.so

. I have a program to parse that file which helps a lot in process injections and stuff. It works fine on most cases. But there is a problem with Flatpaks. They use a virtual path

/app

/app

to refer to the installation path of the Flatpak itself. I need a programmatic way to resolve the

/app

/app

path into a real path. E.g

/app/myapp

/app/myapp

should be like

/home/some_user/.var/org.test.Test/mybin

/home/some_user/.var/org.test.Test/mybin

. Maybe there's a way to disable this virtual path from Flatpak itself, or a way to resolve it using regular Linux APIs?
