What is an example of a securitized debt?

Could you please provide an illustrative example of a securitized debt? I'm interested in understanding how this financial instrument works in practice. Specifically, I'm wondering if there's a real-world scenario where a company or institution has bundled together loans, mortgages, or other forms of debt, and then sold shares or units of that debt to investors in the form of a security. If so, could you elaborate on the specifics of that example? I'd appreciate your insights on this topic.
