How to buy pyth network in the UK?

Could you please explain, in a straightforward manner, the steps involved in purchasing Pyth Network tokens in the United Kingdom?

Additionally, would you mind clarifying the payment methods accepted for this purchase and any associated fees or commissions? Lastly, is there any advice you could offer to ensure a smooth and secure transaction process? Thank you for your assistance.
