How is the wormhole created?

I'm quite intrigued by the concept of wormholes, and I'm eager to understand their creation process. Could you explain, how exactly is a wormhole created? Is it a naturally occurring phenomenon in the universe, or is it something that can be artificially generated? And if it's the latter, what kind of technology or scientific principles are involved in its creation? Also, I'm curious to know if there are any limitations or challenges in creating wormholes, and what kind of impact they might have on the fabric of spacetime. I'm looking forward to your detailed response.
