Q: I want to duplicate the UI behavior but there are no documented ways for doing so.

A: AVS issues undocumented CLI commands; to see what AVS does when you hit a button or otherwise manipulate the UI, do the following:

avs> debug CLIrecord_LUI 1
avs> script -o /tmp/script
net_clear
avs_script> 

At this point AVS will echo back all LUI CLI commands.
