I may have found an answer already in the code...
https://gitlab.com/gambas/gambas/-/blob/master/comp/src/gb.form.terminal/.src/TerminalView/TerminalFilter_VT100.class?ref_type=heads#L158

it does this.....

        If sCmd = "0" Or If sCmd = "2" Then          hView.Title = sTitle

sData at that point has the path to the left of iPos2 that is used to set
the title and it seems to have the prompt to the right

        If sCmd = "0" Or If sCmd = "2" Then          hView.Title = sTitle
          hView.Prompt = Mid$(sData, iPos2 + 1)


I wish there was an easily way to remove escape sequences and convert it to
plain text

All i found was a sed command

Private Sub Prompt_Write(Value As String)

  Shell "echo -n '" & Value & "'| sed -r
\"s/\x1B\\[([0-9]{1,2}(;[0-9]{1,2})?)?[m|K]//g\"" To $sPrompt

End
