How to replace the color of dialog's text buttons?

Question

I'm using a custom theme for my app. When the dark mode is applied, some colors don't match the dark background at all. For example, text buttons for dialogs:

According to the Material documentation, the text buttons use the Primary color. But I've noticed that the default theme (the purple, blue-green one) uses some secondary color for the text buttons, which is what I'd like to achieve.

That dialog is popped up by a list preference, so I can't create a custom activity as dialog to replace it with its own style.
