Text frame inside a text frame - how to add text

I have a few pages that I need to add page numbers to. They already have text frames at the top filled with text.

I create a new smaller text box to add the {@page@} token, but when I click inside the new text frame, it defaults me to the main, larger frame that the text box is within. Is there a way to enter into the smaller text frame to add the necessary token?


There’s another recent thread about the same topic here

Thanks! That was the work around I ended up applying after all.
