Not sure how to install

[dgleba]

Question:

Am I doing this right? What should the result be?
Many thanks for considering my request.

Detail:

I have done the following. It shows in apps - Plain text editor. see next pic.

When I press new text file I see what is in next pic. But, I don't know if that is files_texteditor.

I followed this. https://chatgpt.com/share/67fc6dae-7d6c-8013-b9c2-059024e48aeb
