Schedule retrain an existing prophet model

I am using mlflow to log the prophet model let's name as model1. I am able to log the model, versioning is also happening, and prediction also working fine.
Now i got data for next 1 week since my model was trained, So i want to train my model which should have understanding of previous data / historical data based on which model1 was trained as well as on new data also.
One way of doing that collab all data and train it which in time consuming.

since i am having trained model of prophet:
Is there a way to retrain the model it weekly with new weekly data?
using mlflow i am able to log it and load it, but I don't know how to retrain it with new data.
