Rotate a shape in Google Slides without rotating the text

I’ve used PowerPoint almost all my life – have used Star/Open/Libre Office Presentations as well without much issue. I’m relatively new at using Google Slides.

Here’s what I want:
I’m using the built in shape “Flow Chart Offpage Connector”. Basically, a rectangle with a triangle pointing down. I have it rotated 270 degrees so it points right instead of down. I want to add text to this shape. When I add it, the letters are sideways and going from bottom to top due to the rotation. I want the letters to appear normal orientation and go left to right. How do I do that?

This seems like it should be an easy, straight forward answer but I can’t find it.
