Question on the pv_id

Hello

I have read the documentation on pv_id at https://developer.matomo.org/api-reference/tracking-api#optional-acquisition-channel-attribution

I understand that it has to be unique for a given pageview. So, for example, if a user does 5 actions and assuming i use the javascript to track the user’s actions, they should all reference the same pv_id . Let us say that this pv_id is 111111, and the user is userABC, and the actions are done on page1

Now, when another user, XYZ performs some actions on this page, page1, we should not use 111111 for this user’s pv_id, right?

I guess I am asking if the pv_id is unique per user per pageview

Thanks and regards
