How do I send a cryptocurrency via PayPal?

I'm curious to know, as a cryptocurrency enthusiast and user, how does one actually send a such cryptocurrency as Bitcoin or Ethereum through PayPal? I've heard mixed reviews about this possibility, some stating that it's a straightforward process while others claiming it's not possible at all. Could you clarify the steps involved? Is there a specific service or feature within PayPal that enables this? Additionally, are there any fees or limitations that should be considered? I'd appreciate a clear and concise explanation to help me understand the feasibility of sending cryptocurrency via PayPal.
