Is it difficult to grow Zoysia from seed?

I'm curious, is it really challenging to cultivate Zoysia grass from its seeds? I've heard that it can be quite a task to get them to germinate and thrive. Do you have any personal experience or advice on the matter? Is there a specific technique or set of conditions that need to be met in order to successfully grow Zoysia from seed? Or is it just a matter of patience and persistence? I'd love to hear your thoughts on this.
