What is the command to run gradient boosted trees classification algorithm

I have installed XGBoost version = 1.5.2 . I would like to know what is the command to run gradient_boosted_trees_classification algorithm for training and prediction?
(e.g. for airline-ohe and letters datasets)

You should look at the documentation on their website. https://xgboost.readthedocs.io/en/stable/get_started.html
