How to log model using mlflow REST api? Does mlflow REST APIs support it?

I'm writing a library using mlflow REST APIs. I'm looking for mlflow REST api for logging different mlflow models.

In the doc, https://www.mlflow.org/docs/latest/rest-api.html#log-model it says the api will be removed in future and doesn't have description about model_json request body.

If I see github, https://github.com/mlflow/mlflow/blob/master/docs/source/rest-api.rst mlflow REST API for Log model is missing.
