How do I transfer money from Coinbase to PayPal?

Could you please explain the process of transferring funds from my Coinbase account to my PayPal account? I'm not familiar with the steps involved and would appreciate a detailed breakdown. Are there any fees associated with this transfer? How long does it typically take for the funds to arrive in my PayPal account? Also, are there any security measures I should be aware of when making this type of transaction? Thank you for your help.
