“Delete Copilot interaction history” feature (MC715415)

Hello ladies and gentlemen!

Recently, MS issued MC715415, according to which users are able to delete their Copilot interaction history themselves.
I wanted to ask your experience, has someone already tested it and what is in the scope? - Conversation history in M365Chat or/and facts of feature use within other Office services (that can be found in audit logs for example)?

Thank you!
