Is there a callback that can be used (where a mixin can be added) for when a checkout step is displayed?
For example, there is the
navigate function for each step that is called when the checkout is loaded directly to that step.
So if you access directly the url
checkout/#some-step and there is a step with the code
some-step then the function
navigate from that step js file is called.
Is there similar for when a step becomes active?
Note: need this for a custom step, so I can change the code in that step without restrictions.
