annot find Pi Pico Micropython Device (Ubuntu)

Hi,

I am using PyCharm Community 2023.3.5 on Ubuntu 22.04

I have installed the MicroPython Extension.
I have put myself in the groups dialout and tty as I wish to connect to and use a Raspberry Pi Pico.
According to the Arduino IDE2 it should be accessible as /dev/ttyACM0 or /dev/ttyS4, both of which the Arduino IDE2 can access.

The Pi Pico is displayed via lsusb as Bus 001 Device 013: ID 2e8a:0005 MicroPython Board in FS mode.
Unfortunately try as I might I cannot get PyCharm to accept/detect either of these 2 devices from within the MicroPython extension.
Clearly I am doing something wrong within PyCharm as they are addressable from other IDEs.

Any advice gratefully received.
Thanks.
