Accessibility navigation best practices

Hello! 

It feels unintuitive to ask the user to click the player's "next >" button when there is button interaction on the slide. We also don't want to user to advance until the buttons are interacted with, so some conditions are needed anyways. 

Is there a reason to keep the player's "<prev next>" navigation at all for accessibility? They also have to tab through all the other player features to reach it, versus a button where we can control the focus order.

Any thoughts or resources would be most helpful.

Thanks!
