How exactly do I "re-authenicate" the Zoom Events for Hubspot integration?

I received the email a few days ago telling me I needed to re-authenticate by Feb 1st

Maybe I am being an idiot, but I don't know what I am supposed to do in order to complete this task?

I have gone to the Zoom Events for Hubspot app in the Zoom App Marketplace, but then what do I do?

There are images relating to adding the email addresses, but that's step 2.
