[Python] How to capture arbitrary paths at one route in FastAPI?

by this React app get served and React routing also works fine at client side but as soon as client reloads on a route which is not defined on server but used in React app FastAPI return not found to fix this I did something as below.

• @app.route('/network')
• @app.route('/gat')
• @app.route('/session')

async def renderReactApp(request: Request):
return templates.TemplateResponse("index.html", {"request": request})
