How to make textport visible in perfome mode

I am making cms using a touch designer and found a way to check the ping with textport.
The reason I came to textport was because I was inspired by Lagand’s base_printDispExample.
I downloaded the file he uploaded, but I don’t know how to use it, so I want to know how to solve it.
I want to make textport visible in perfome mode, so I would appreciate it if you could tell me how

Alt-t or the script command: ui.openTextport()
