Btw when is your flight? QR currently arrives at Terminal 1, not 2A/2C which is closed (until end 2025 at least?).

According to the Paris airport website, you can take the blue bus from Terminal 1 to 2F/2E-hall L (both terminals are connected). The bus line is in international zone.
After leaving the bus, you can walk to 2F (a few minutes away). The passport control will be just before entering 2F.
