I would say ask for feedback from the team you are leading in an honest way and evaluate what you get back and try your best to change if it makes sense.

Usually your actions affect them the most and if you do something that "annoys" them(e.g. Too authoritarian, micromanaging, Not giving the credit when due, Not defending them against external forces etc.), most would not approach you from below to mention it(exceptions exist), after all you are the lead/manager imagine how you would(or would not) give feedback to a Senior Director if they did not ask for it. Giving unsolicited feedback is also weird and some people don't receive feedback well, so them making the first move is all but risk unless they know you want it.

Not every feedback makes sense and not every person can give feedback properly(being too shy or too harsh etc.). You would also need to learn how they communicate their concerns and calibrate what they say. For example "I don't like X because Y" of a very introvert person carries more weight than same sentence of someone that can easily discuss things they don't like openly.

Edit: As you have asked specifically for books, I can recommend "Making of a Manager" by Julie Zhuo. It is a very good and structured read.
