How does the tech_indicator_list work in the env_kwargs of FinRL?

"tech_indicator_list":processed_train.columns[7:]

Right now, the above code runs correctly for me. My processed_train.columns[7:] has all the technical features and some other macro features as well.

Now given that there are both technical features and macro features in processed_train.columns[7:], can FinRL correctly identify the technical features from the mix of technical and macro columns?

And will FinRL use only the specific TIC`s technical features when the above code is used ?
