Text Wrap - Intelligent Subject - Contour Options greyed out
Hello.
For the first time, I'm trying to lay out a print ad in InDesign rather than Illustrator. I'd like to wrap my body copy around the subject of an image. I saw that InDesign should have a feature called Intelligent Subject Detection. I've followed the steps shown here, under the heading "Wrap text with intelligent subject detection", but I do not have access to "Contour Options".
I have my body copy in a text frame. I have the main image filling the entirety of the live space and bleed using a graphics frame. Text frame is floating above the graphics frame. I have only the text frame selected.
I am using InDesign 16.4 on a early 2013 MBP Retina running macOS 10.15.7.
I'm hoping the solution is a simple thing I am overlooking.
Thank you in advance for your advice.
