Purge cache for a single user’s private cache

Hello, I need to purge the cache for a single user’s private cache. I believe I could use the hook ‘litespeed_purge_private’, but the official documentation doesn’t specify how to do it.

I’m trying with; ‘do_action(‘litespeed_purge_private’, ‘user_’ . $user_id);’, but I’m not sure if it’s correct. Could you please assist me?

Thank you.
