How can I buy Saudi stock?

Excuse me, I'm a bit confused about the process of purchasing Saudi stock. Could you please explain the steps I need to take to acquire shares in the Saudi stock market? Are there any specific requirements or restrictions I should be aware of? Additionally, is there a preferred platform or brokerage service that you recommend for conducting these transactions? I'm eager to learn more and start investing in Saudi Arabia's financial market. Thank you in advance for your guidance.
