How to create/train sentence embedding model

I have a file of a few thousand sentences I'd like to convert into something that NLEmbedding can use. (In searching around it looks like none of the sample code for "Make Apps Smarter with Natural Language" from WWDC 2020 was ever released.) Can anyone put me on the right track on how to do this?

Never mind. This question is incorrect perspective.
