Facebook Pages - Watch posts (public pages) - Does not really get them

Hello Make community!

I am trying to build an automation which is whatching continuously 10+ facebook public pages and collects their content into a speadsheet.
so far I am having trouble with this one because it does not give me clear results for each pages.

Also I read that I need to be an admin:

But in this case I do not understand the purpose of this module.

Does anyone have a solution for this?
