How to get Dubai citizenship?

Could you kindly explain the process of acquiring citizenship in Dubai? I'm particularly interested in understanding the eligibility criteria and the steps involved. Are there any specific requirements that need to be met, such as financial investments or residency periods? Additionally, I'm curious about the duration of the application process and any potential challenges or complexities associated with it. It would be helpful if you could provide some insight into this matter. Thank you in advance for your assistance.
