Pack precompiled C++ app with multiple .so dynamic libraries

Hey. Is it possible just to copy precompiled libraries and binaries via flatpak manifest file?
This is example manifest library

app-id: com.hello.superkek
runtime: org.freedesktop.Platform
runtime-version: "22.08"
sdk: org.freedesktop.Sdk
command: superkek
  - name: Superkek
    buildsystem: simple
      - install -D superkek /app/bin/superkek
      - install -D /app/bin/
      - install -D /app/bin/
      - type: dir
        path: temp

After I’ve compiling single bundle and trying to run it, I see that supekek need to launch. Should I manually copy such 3rdparty libraries dependencies or what the plan?

Just build from source.
