If you look at the example image on https://developer.apple.com/documentation/clockkit/clkcomplicationtemplategraphicbezelcirculartext the circular template used in the middle (which is also available as a standalone circular complication) has no image or gauge, just two rows of text.
However, none of the templates listed on https://developer.apple.com/documentation/clockkit/clkcomplicationtemplategraphiccircular allow this. How is this acheived?
