I have the same issue, I created a drop down menu with a Yes / No label and true/false value.
Its not as clean but it did the job for now.
I havent tried this but you could also try creating your own button with a yes/no text. only have one of them visible of course.
Create a Boolean variable. In a workflow change the variable on click so each time its clicked it switches between yes and no / true and false.
Use a state change on the button and in the condition set it to the same boolean variable in the workflow.
but also, if you want to be able to update the item in the list you will have to do some extra things that is shown HERE
If you already know all this you can ignore me
