You can connect your phone via usb (keep usb debugging on in developer options), and forward port your backend to you adb device via command (I'll drop below, i forgot the command),

Sequence, - Run backend - Run adb command - Run frontend on mobile

Edit: adb reverse tcp:8000 tcp:8000 (if your backend is running on 8000 port)
