how to transfer a file by serial, 1K-Xmodem protocol

[jiew0136-ui]

the environment is Windows11, windterm 2.7.0
When I use the transfer pane to transfer files, it displays an unrecognized error message and prompts me to install lrzsz first if lrzsz is not detected. However, I have chosen the 1K-X modem mode. Is there any expert who can explain how to send files through the serial port in Windows 11's windterm2.7.0
