Is stock lending a good option? How safe is it? What are the pros and cons?

I have been investing for a couple years now and I have been seeing mentions of stock lending recently. I read that it was relatively safe but I’m a little skeptical. If I were to do it are there certain stocks or sectors I should lend or does it matter? How much of my portfolio should I lend? For a little more context the stocks in my portfolio are Bank of America, AT&T, Exxon Mobil, Coca Cola, Realty Income, Chevron, Disney, Enterprise Products, Tesla, and Microsoft. Thank you for your help.
