How to buy SLP using GCash?

Can you please explain the step-by-step process for purchasing SLP tokens using GCash? I'm interested in investing in SLP but am unsure about the exact procedures to follow when using GCash as my payment method. It would be great if you could provide clear and concise instructions, including any potential fees or limitations I should be aware of. Additionally, could you also mention any security measures I should take to ensure a SAFE and secure transaction?
