Advice on Kwai fah cuttings

[Punaperson]

Cleaning out a long neglected corner of my yard, I found a Kwai fah ( Osmanthus fragrans ) plant that I had forgotten I had planted years ago. It's very tall and straggly, and will need pruning. I found several sources online that let me know how to revive it, but nothing on how to root the cuttings that I'll have after pruning. Does anyone have experience or advice on what's the best way to get them going ? Thanks in advance.
