How can i use Selenium Webdriver inside flatpak Eclipse?

Hi guys im trying to run chromedriver and geckodriver for firefox inside an Eclipse project, but flatpak Eclipse app cant open Firefox or Chromium because Eclipse does not have access to the binaries of the system, i have tried to give access to the binaries using flatseal but nothing works:

PATH=/app/bin:/app/openjdk-11/bin:/usr/bin:/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games:/snap/bin:

**This is the Eclipse error log:**
Scenario: Login in to account with correct details # src/test/java/FeatureFiles/Login.feature:47

When i try to execute my code with a local Eclipse installation everything works fine.

Is there a way to give flatpak Eclipse access to the flatpak Firefox or chormium binaries?

Start with the failing entry point at StepFiles.Login.setup(Login.java:29) and the scenario in src/test/java/FeatureFiles/Login.feature:47. Review the FirefoxBinary and FirefoxOptions stack-trace context alongside the Flatpak Eclipse and browser setup described in the issue. Done means documenting a supported way to run the scenario in Flatpak Eclipse, or clearly recording the relevant limitation.
