Using serial for web client

Error observed in browser console when connecting over serial interface:

Uncaught (in promise) NetworkError: Failed to execute 'open' on 'SerialPort': Failed to open serial port.

System logs:

The user probably needs to be member of dialout group to access serial port

sudo usermod -aG dialout $USER

For this purpose, using chromium:

sudo flatpak install org.chromium.Chromium

Set the override:

flatpak override --user --filesystem=/run/udev:ro org.chromium.Chromium

Confirm change:

flatpak info --show-permissions org.chromium.Chromium

Close and re-open the browser.
