In order to proceed, you will need your Facebook account which has access to your pages and you'll need to be an Admin in PeopleVine.
Go to the company settings and click on integrated platforms, where you'll see an option to authenticate with Facebook.
Click the button to sign in with Facebook and then login to your Facebook account.
You will then be prompted to approve access and select which pages you'd like to provide access. Don't worry if you add one by mistake, you can easily remove in PeopleVine.
Confirm the options that you want to provide access to, keeping in mind some things won't work in PeopleVine if you disable it.
