Removing text box outline

I can’t work out how to remove my text box outline in Layout. Could someone please help?

Stroke under Shape Style.

Thank you. Do I have to select that before I draw the box? I can’t change it once it’s placed?

If you select the Text tool and go to Shape Style you can turn off stroke for future text boxes. If you want to remove borders in existing ones, select them and then go to Shape style.
