Transperent USB port monitoring = serial sniffer tool?

[PizzaProgram]

Sorry for asking it here, but I see there are many clever minds working on this repo and maybe someone can answer me:

• Is there any app with GUI that I could run on RPi OS

that would allow me to monitor communication between RPi-4 + an USB connected RPi-Pico without ?
Something like this, but for Debian based RPi-OS (64bit).

I'm trying to improve ConfigurableFirmata and be able to find disconnect-errors. (Sometimes after 3 minutes, other times after 3 days...)

What are You guys usually use while testing this repo? Thanks for any hint in forward!
