Output from orachk Growing; How do I maintain?

Hello

We have RAC on OLinux 7.9, CRS is 19.3. We installed the AHF, with TFA Version 21.2.4.0.0. The retention period I see with oswatcher is 30, but I'm not clear on the relationship, if any, to the volume of diagnostic bundles ( orachk*.zip) that is retained in subdirectories off orachk/user_root/output. As of now, I have hosts with 9 months worth of content off this path, and I need to clear space.

How do I manage the content created by orachk? For now, I'm going to drop content older than 30 days, but I'd like the proper configuration to manage this automatically. I'm new to AHF, so please forgive the newbie questions. I'm confused by the many acronyms.
