AS instead of WITH NAME

I updated robotframework from 5.0.1 to 6.0.2. As I see Robotframework has changed the use of WITH NAME for custom library to AS (Robot Framework User Guide). However, when I changed the WITH NAME keyword to the AS keyword, Pycharm gives me an error and does not find the keyword according to the new convention. I know WITH NAME can still be used, but the Robocop rule (Rules list - Robocop 4.1.1 documentation) recommends using AS.
Do you know how to set PyCharm to recognize AS for a .robot file?
