How to buy pyusd in PayPal?

I'm curious about how one would purchase PYUSD, a hypothetical cryptocurrency, using PayPal. Could you elaborate on the steps involved in this process? Does PayPal directly support PYUSD transactions, or is there a third-party service that facilitates the purchase? I'm interested in understanding the security measures taken to protect users' funds during this process, as well as any potential fees or limitations that may apply. Additionally, could you provide any insights into the potential risks associated with buying PYUSD using PayPal, and how investors can mitigate these risks?
