OpenCV dependencies

Question: I have recently contacted support because of an opencv problem I had. They told me I would be using a wrong template so I tried forking the repl they have shared but run into a problem I already encountered earlier. I attached an error message and the code below. It seems like some dependencies are missing. How can I manually fix this on my own without running it by the Repl Support every time?

Error Message:

qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "/home/runner/Python-OpenCVjjj/venv/lib/python3.8/site-packages/cv2/qt/plugins" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: xcb.
