Let’s say you’re tuned into an approach frequency, and want to do this - unless the controller tells you to, I’d say to just pay very close attention to what’s going on around you and continue inbound. The controller will respond to you when they can.
If you notice that the airspace is crowded and can infer that the frequency would be very busy, I’d say you can put yourself in a holding pattern before reaching approach, perhaps?
Moral of the story is that while you’re tuned into ATC, don’t do anything they tell you not to do, and follow all of their directions. Also, be sure to not do anything that you weren’t told to do. That would be an example of not following directions as well because you weren’t told to do it.
