Narcissism insights in Buddhism

I've been recently observing that I am surrounded by a lot of narcissistic people which include all kinds of relationships friends, family, coworkers and acquaintances. Having been surrounded by these people I believe I have developed a relatively weak ego/low self-esteem over time -which of course translates to suffering. I also have been doing some meditation related work which has made me stronger/confident and also I believe it is the reason I've been recently having clashes/fights with these kind of people. Thus I wanted to understand narcissism from a deeper perspective of Dhamma. Modern psychology has it already in the dark triad personality traits, namely, narcissism, machiavellism and psychopathy. I watched and analyzed some videos from Jordan Peterson and some others; but I am shocked to find such a surprising lack of material and insights about this phenomenon from any good spiritual gurus, and even here on forums like stack-exchange, reddit etc. Thus I am making this post! So I would like to plead here - kindly contribute any deep/thorough analysis of this trait both from classical sutras perspective and from your own understanding: giving arguments/analogies/reasonings for any assertions. Possibly include the following topics - deconstructing what narcissism actually is, what kind of mental states and defilements are involved, how to overcome those as a person who has narcissism and how to minimize the bad karma recieved while dealing with such people. It may be a little bit of effort to write up properly, but I believe you sharing such valuable insights will be very helpful - for both people like me who have to deal with narcissistic people and also for others who want to fix their own narcissism and corresponding defilements. If anyone does contribute here, your efforts and insights are greatly appreciated, Thank you!
