GetKeys from UMovieScene

Comrades, good afternoon.

I can’t understand it.
I have a UMovieScene object.

The MovieScene module has an FMovieSceneFloatChannel structure https://vk.com/away.php?to=https%3A%2F%2Fdocs.unrealengine.com%2Fen-US%2FAPI%2FRuntime%2FMovieScene%2FChannels%2FFMovieSceneFloatChannel%2Findex.html&cc_key=

, from which you can get the keys, by the Getkeys function.

The question is, how do I get this structure from my MovieScene and then the keys, since I can’t figure out how to do it
