Raspberry Pi Pico micropython ModbusRTU

Hey,
I wan't to use modbus library in pico. First of all, I just try ModbusSerial. I am trying to use this https://github.com/techbase123/micropython-modbus github source.
To start I want to write a simple number using modbus poll, pi pico is connected to my computer via usb. Can I read the value I wrote directly from the computer via modbus without using any transmitter?
I want to use serial communication used at https://github.com/pycom/pycom-modbus/b ... er/main.py but it mentions uart pins.
I am beginner. How can I send data with using modbusRTU micropython on pico. Is there any suggestion or example library for that ? Additionally, I don't know how connection should be? Should I use transreceiver or sth like that or usb port enough for reading this datas with modbus poll on windows.
